I get 

dmesg | grep -i agp
Linux agpgart interface v0.99 (c) Jeff Hartmann
agpgart: Maximum main memory to use for agp memory: 439M
agpgart: Detected Via Apollo Pro KT133 chipset
agpgart: AGP aperture is 128M @ 0xe0000000
Fire GL built-in AGP-support
Based on agpgart interface v0.99 (c) Jeff Hartmann
agpgart: Maximum main memory to use for agp memory: 439M
agpgart: Detected Via Apollo KT133/KM133 chipset
agpgart: AGP aperture is 128M @ 0xe0000000
Power management callback for AGP chipset installed
[fglrx] AGP detected, AgpState   = 0x1f000217 (hardware caps of chipset)


I assume the part after Fire GL is the inbuilt agpgart I was speaking about. 

Hmm... I wonder if there is some conflict between the 2 mods? Maybe I should 
remove agpgart?  I will try that after I post this.

Sorry, yes should have said
MB = AOpen AK73 1394 (Via Apollo Pro KT133 chipset)
CPU= Athlon 1.2
Kernel= 2.4.22-21mdk
Graphics = ATI Radeon 9200se 128Mb
Driver = fglrx-glc22-4.3.0-3.2.8 (from ATI)

Erm... no. Docs do not mention anything like that.
