It's also worth considering that a clock for clock comparasion between a PC and a Laptop will always show the laptop to be slower.
The Processor, Video Hardware, Drives etc are all optimised for power consumption and size...not speed.
The Mobile P4 operates without a bloody great H/Sink fan and draws less power, how do you think it achieves that ?
I'm guessing that you have a 8200, Your Gforce 4 Go graphics chip is compareable to a GF2 on a desktop system, again due to power and size considerations.
You could have a tinker with the power management setup, it may be set to "Battery Economy" rather than "Performance" The Processor in question is capable of speedstep after all, it may be possible to use the Bogomips value to determine what speed the clock was actually running at, but this is only measured during boot AFAIK.
In short
Don't expect your laptop to ever perform as well as a 1.6 Ghz desktop system, although that said slower than a 1Ghz does sound a little off, check those power settings.

I mentioned in an earlier post my move from a P!! igig PC to a new dell laptop with a P4 1.6 gig and how with rh7.3 it seemed slower than the old system. I have now investigated this a little further.
One other factor here i think you are saying a PIII 1Ghz to a PIV 1.6Ghz? in which case the performance would not be 60% greater, in all likelyhood a PIV at 1.6ghz will most likely be the same speed as a PIII 1Ghz for most of the time, slower for some things and faster on a very few others.
Have you also checked memory timings in the Bios? is the kernel built with support for a PIV, are you using a framebuffer driver for X or native GFX support? Are there many unused daemons running in the background that you don't need? are all other things to check.
About hdparm, PIO modes are usually discovered by the BIOS pretty accuratly so I would leave them alone, setting DMA to 16bit or 32bit with sync is usually safe and the other options are trial and error. You could try looking on the net to find other peoples settings, linux on laptops page may be good for this (this machine is a laptop?) as would looking on the disk manufacturers webpage for specs too.
Oh and finally hdparm can destroy data on your harddisk if you go for too many settings and the disk/computer doesn't like them....

Hi,
As a concrete example of hdparm, here are my settings:
/sbin/hdparm -X66 -d1 -u1 -m16 -c3 /dev/hda
You will need to run this every time you boot the computer.
I understand these are very standard settings for even vaguely modern hardware, so they should be safe although as always, it's your liability. I think you know you can test your drive's read performance using hdparm -t, so try this before and after.
Distros have to be safe by default, so they don't use hdparm. I don't really see why there isn't a deb for it though (with debconf to set it up - I think hdparm.deb just gives you binaries/docs).
