It appears that it should be covered by the RealTek driver The way FreeBSD and others detect it is as 0x802910EC which is the PCI id for the ne2000pci driver in Plan 9 also.
Not sure if this is relevant but during 9load I get: pcirouting: South bridge FFFF, FFFF not found I believe that's also what Parallels shows to other OSes as well... I've tried to add 0xFFFFFFFF to the kernel in /sys/src/9/pc/pci.c but this hasn't fixed anything for me... I think I saw an email about someone adding more NE2000 support to 9load earlier today, I'm going to play around with this a bit more before trying other things but if anyone has any pointers I'd be happy to try them out. Parallels is soooo much faster than QEMU on Intel Macs that it's totally worth the extra pain to support it. Even Venti seems fairly snappy here (though this may be due to other enhancements Russ has made since I last tried Plan 9 in an emulator) Dave
