Splack and SUN Sparc Ultra 5

Hello World!
I\'ve a big problem with Spalck and the Workstation Sun Ultra 5 360MHZ(256 Mb)
I can\'t start KDE,i can\'t configure xf86config ....i don\'t know why!

For example,the installation is OK...after the login i configure X-window with xf86config.
The VGA onboard is ATI MACH64 with 4Mb ram,i hope so....but when i type the command \"startx\" there is this error:
\"Can\'t load module for VGA CARD\"
if i chancge the module of video card the problem is the same....


Can you help me?

I\'ve the standard Sun Sparc Ultra 5 and i can\'t start KDE.....:-(
