Compaq V5000 and eCS 2.0RC4 HELP!

Hey, my roomate is trying to get eCS 2.0RC4 working on his Compaq Presario 
V5000, and we have had some limited success so far. here are the hardware 
specs:
Laptop:
AMD Turion64
ATI Radeon x200m
15.4" LCD (1280x800x32bppx60hz)
60gb HDD
1.5gb RAM
Realtek 8139 NIC
ATI/Conexant Sound

So, we got ACPI 3.05/3.06 to function corerctly with the /!NOD switch, but 
we can NOT get his display to work properly. If we set it to the native mode 
using SNAP it will scroll the desktop. Trying the "lcdusebios off"
switch in 
gaoption will result in SEVERE graphical corruption and flickering on the 
next boot. Panorama did not work on the first install because the WPS class 
wasnt registered and we had not figured out the ACPI switch yet. So, if you 
could, please help us so we can get his computer to work with eCS. Its very 
close :C

Thanks!
