	You mean like you have to set the latency timer to 0xFF?

no, that's an errata for the 3c59x cards. the important erratum for the
3c905 concerns it hanging if you do busmaster receives at 10Mb.

you do not need to set anything in the pci config space for the 3c905,
the card and bios should have set it correctly (they do on every system
i've tried).

if there's interest and a volunteer i can give them the current brazil
driver provided they promise to give back a plan9 version for inclusion
in the website updates. it will be a bit of work:
