Your laptop is pretty old and googling I found that it has an ATI RAGE 
GPU (though the info above says MACH64RM).  I think you'd need the old 
Mesa mach64 or r128 driver.  Those drivers were removed from Mesa 
after the 7.11 release, about a year ago (and even then probably 
haven't been tested in years).

So you'd have to build/install an old Mesa release (and maybe some old 
drm/kernel drivers too).  But since that's old code, it's hard to say 
what problems you might run into.
