Very nice find, I wasn't aware of this riser. The AGP side seems compatible with the Pegasos 2 and the (64-bit) PCI side seems compatible with (32-bit) Radeon HD cards. Would be cool if someone tried in his Pegasos and compared performance with the same Radeon HD card installed directly in 33 MHz PCI slot.
Exactly this I have in plan. I want to buy this riser, and wait for some cheap HD 4350 PCI. I don't need 3D, but want video accel, thus HD 5450 have no sense for me (yet). And if it will work and be faster then Radeon 9800, I try to produce riser that fits to Pegasos.
Right to say, that this plan is very very long-term...
