I presume this means that my Fire GL1000 Pro card *can't* support 1600x1200 with 24-bit colour depth. That's where assuming things gets you to.
It "should" do 8MB is enough memory for 24bit at 1600x1200
1600x1200 = ~ 1.9 megapixels x 3 bytes per pixel (for 24bit colour) = 5625 KB Even allowing for the fact that some cards do the allocation internally at 32bit when asked for 24bit depth you still have enough video ram.
Your RAMDAC is running at 230 MHz which is enough for a 90 Hz refresh at 1600x1200
Technically there is no reason why the card cannot display 1600x1200 with 24bit colour depth.
Exactly, those are the sums I did too, which is why I had assumed the card would support 1600x1200 at 24-bit. However I'm not going to waste any more time on it as for 90% of the time I use the Linux box via the X Server on my Win2k machine. It's just an occasional convenience to switch to viewing it directly and a reduction to 16-bit colour depth isn't a problem. The lower resolution *was* a problem though as it meant my predefined xfce screen layout was overlapping and off the screen.
