Presario 900 X Problems

[Vaughn Treude]

Hello all:
	A week or two ago I posted some stuff about a Compaq I was trying to install 
Linux on.  After a lot of trouble, I was finally successful - installed 
Mandrake 8.0 with a 2.2 kernel, because 2.4 couldn't handle the IDE chipset.  
There was a second problem that I didn't fix which I'd like to address now:  
I couldn't set the screen resolution higher than 800x600, even though I know 
it goes up to 1024x768 (that's the default resolution in the XP installation 
that came with the machine.)  The problem may be with the video chipset - 
it's an ATI Rage Mobility U1 - there are a lot of versions of ATI drivers, I 
can tell you, and not many references on Google to that specific version of 
Mobility.  There isn't a reference to the Mobility U1 in the list of graphics 
cards in the Mandrake control center.  However, I did find something on 
Google that said the Mobility U1 should use ATI's Radeon M6 driver.  Mandrake 
does have a Radeon card in the list, but whenever I select it and try to 
change the resolution, it gives me an error that says "screens not found" or 
something like that.  (Mandrake doesn't select the right card by default - it 
selects 3D Labs Permedia, on which I can't change the resolution either.)
	I was wondering if I might need to install a radeon kernel module.  I did 
find a "radeon.o" module in the 2.2.19 kernel support on the Mandrake CD.  
The problem was that when I tried to do an "insmod", it complained about a 
whole bunch of undefined symbols.  I'm not sure how I can find where those 
symbols are located, and if I do I'm not sure if I'm pursuing the right path.
	Anyone have a similar experience that could shed some light on this problem?

Thanks in advance,
