Yes. A few soundcards and network cards works well.
And drivers ISA devices that is endian independent maybe works well, too.
(ex. SoundBlaster, realtek8019 based ne2000 compatibles, and so on.)

The card that works on Motorola's PReP is the special card for its
own, I suppose.
Any devices that doesn't control under PPC-Bug (= cannot check on
PPCDiag mode) works well if kernel have its driver.
The PReP machines load zImage(= compressed kernel) from type41h
area. PPCBug works till this action.
All devices on PReP machine wake up with the zImage itself, not PPCBug,
if under Linux.

Yes.

The default config for PReP is on the kernel source, I suppose.
And if you build it, write out the zImage on fdd, and boot from it.
That is the useful check for PRePs.
If it is good, write it on the PReP bootable area(= type41h HDD partition)
Best regards.
