Which would be a faster striped RAID 0 setup on a B&W G3 - motherboard ATA with one disk per channel and a Firewire boot disk, or a homebrewed Firewire RAID with a normal ATA boot disk?

Yes I'm too cheap to buy a PCI RAID card.

Depends

It depends upon how you set it up. I believe the B&Ws only have one Firewire bus, so both drives would be sharing the same bus. If you do it ATA, and have both drives on seperate buses, then it will probably be faster, though it kind of depends upon how Apple set it up. Your best bet is probably to get yourself a PCI Firewire card and set up your RAID Firewire on the 2 seperate Firewire buses (built-in and PCI). That would be cheaper than geting a RAID controller, but would make the speed better.

Onboard IDE

I seem to recall that the secondary IDE channel in the B&W doesn't support UltraDMA. (33Mb/s)

Oooh, I'm right:

http://developer.apple.com/documentation/Hardware/Developer_Notes/Macintosh_CPUs-G3/PowerMacintosh_G3/PowerMacG3.38.html

In which case, using the secondary channel for a hard drive is a pretty poor idea.

Just as an aside, I imagine 2 Firewire drives (or two Firewire bridge boards + 2 IDE drives) would probably cost more then two drives + a PCI IDE controller. Or at least be very similar in cost.

Eeewww...

Yeah, that would be a problem... Looks like either getting a PCI ATA contoller or the aformentioned Firewire setup are your best bets.
