i am currently using slackware 10.2 with 2.4.31 kernel
i have ati radeon 9200 AGP card and builtin too VIA KM800/KM400

whenever i try to load agpgart it gives me the following message (pasting the message from dmesg)

Linux agpgart interface v0.99 (c) Jeff Hartmann
agpgart: Maximum main memory to use for agp memory: 439M
agpgart: Unsupported Via chipset (device id: 3205), you might want to try agp_try_unsupported=1.
agpgart: no supported devices found.

I dunt know wheather it is detecting my builtin VGA or THE ATI AGP CARD

Some one on #slackware told me to download and compile the new kernel so i downloaded the Kernel 2.6.17.8 compiled it and boot from it
agpgart loaded successfully
Then i download a driver from www.ATI.com and installed it 
when i try glxinfo i got the following messeages

/glxinfo > /home/umair/glx.txt
X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  142 (XFree86-DRI)
  Minor opcode of failed request:  5 ()
  Value in failed request:  0x45
  Serial number of failed request:  27
  Current serial number in output stream:  27


then i try 'radeon' and 'ati' as well in xorg.conf  then in xserver
well its hard to define what i saw in xserver b'cuz every thing was shown more then 100 times anyhow i opened the console by shortcuts and do stuff like
./glxinfo > /home/blah/glx.txt
the result was same as now in Kernel 2.4.31
that is
