I dropped in a standard Radeon 7500 PCI from the PC sector. It does work somehow, but just as standard-VGA adapter with 640x480.

How is it shown in SRM if at all?

Regarding the RAM maybe it's an issue with different timings. I'll try with the kingston sticks alone.

I have two modules of each of the following unbuffered ECC DIMMs installed in my PWS 500au, providing a total of 704 MiB of RAM:

• MemoryWorkx MXK128/DCPW43, 64 MiB - unfortunately no info on the WWW about the DIMM, but the chips are KM48S8030BT-F10 good for 100 MHz
  
• SEC KMM374S403CTL-G0Q, Compaq part # 268308-002, 32 MiB, PC66 compliant but according to the datasheet can run at up to 100 MHz
  
• Kingston KVR100x72C2/256, 256 MiB, 100 MHz
