It's a shame the WiFi and SD aren't working, there's a project on SourceForge to write a WiFi driver
Which chipset? If it is the Atheros 802.11g then dig around on the MadWiFi Wiki http://madwifiwiki.thewebhost.de/wiki/ for more info about the madwifi driver.
Specifically for installing/configuring in mandrake 9.2 using a LevelOne WNC-0300 card: http://madwifiwiki.thewebhost.de/wiki/Ath0OnMandrake92
Dig around for the driver and other info.

PS You can get a Thinkpad T23 for a similar price with DVD-reader/CD-RW combo, working sound, nic, volume keys, screen light, hibernation/suspend, USB (1 not 2 tho'), PCMCIA, modem and over two years' warranty. S3 savage video but no 3D. No bluetooth or built-in wi-fi.
