unresolved symbols and other problems

Hi,
I have posted similar messages to this this in several groups as I haven't a clue as to
what exactly is causing the problem.

I have an old laptop - Fujitsu Lifebook 780Tx which I want to use as an X terminal to my
main PC.
It came with win98 on it an I shrank it to about 1Gig ( the disc is 3.2Gig )
and installed vector 5.1 standard ( a slackware based small distro )
It gives me to choice of kernel 2.4.29 and 2.6.12 at boot up.

Now if I boot the 2.4.29 kernel then X starts okay and I can use it with icewm
but I cannot use my pcmcia network card an Asus WL-107G so I cannot access my main PC.

Before setting up with ndiswrapper I run depmod -a I and get a series of
'unresolved symbols' errors relating to wlan.o, wlan_acl.o etc ath_hal ath_pci.o etc
so don't set up the driver with ndiswrapper.

I downloaded the 2.4.29 source and compiled it and ran

make clean && make dep && make && make modules && make modules_install but it still complains.

If I boot the 2.6.12 kernel I get no unresolved symbol errors so I can use the network
card with ndiswrapper

but if I start X then the mouse goes crazy and menu's appear and disappear at will. so it
is unusable.

I am running version 6.8.2 of X and trying to use the same xorg.conf file in each case.

I would prefer to use 2.6.12 but 2.4.29 would be fine if I can have network and X


Any ideas please?
