The SB0020 (which appears to be a Soundblaster Live! based on a emu10k1) should be compatible, assuming it works.

The SB0410 (being a Soundblaster Live! 24-bit based on a CA-0106) will not work.

Basically any emu10k1, emu10k2 (CA-0100) or emu10k2.5 (CA-0102) based audio card should work.
The wikipedia links above are pretty good for checking individual model numbers.
A few envy24HT based cards also work, although I've not personally tested them in a Powermac.
