My HDSP soundcard isnt recognized when its in the first pci slot. It works alright with the chameleon 1.x or older pc-efi. If i turn hpet off from the bios or just use different pci-slot, the card is recognized. This happens in both leopard and snow leopard, seems to be bootloader related thing.
Gigabyte p-35 ds3r
rme hammerfall dsp (pci)
