Linux-PPC, 802.11g, and B&W new world power mac, internal v.90 modems?

[Brandon Lewis <dotsony@earthlink.net>]

I have a PC with an 802.11b wifi card running debian linux. Currently 
it's supported by the madwifi project, using the atheros chipset. It 
also requires a PCI 2.2 compliant motherboard. Does the B&W g3 have a 
pci compliant motherboard? Where can I find information like this about 
other mac models? Also, is there any way to use drivers like madwifi 
with non-x86 hardware (possibly through emulators or has the proprietary 
core been ported yet?)

Also, to what degree are the internal v.90 modems supported? What device 
do they usually show up as?
