Yes, the 905B is a piece of (explitive deleted). It is not fully PCI
compliant. The original 905 (note the lack of a B) is functional. I don't
know the state of the 905B driver under Linux but I'd recommend staying away
from their NICs based on my experience with the 905B (and "C" which is
an
updated version of the 905B).

Yes, this is true, however the latest drivers (in the 2.2 kernels) have all
these worked out except for a multicast bug. The multicast bug only comes
into play if you have IP Multicasting enabled in the kernel and are doing
several multicast packets (i.e. running an MBone server or something).
Plus, those cards go through some serious testing since 1) Linus uses them
at work and 2) a lot of Transmeta uses them at work.
I have 2 machines (P90/24MB RAM and a K6-233/64MB RAM) at home connected on
a 100mbps hub with the EEPro cards. They work like a charm and get very fast
throughput. I haven't measured it because I'm limited by the disk drive.
The
P90 is still usable while sending/receiving a huge file provided I'm not
hitting the disk much.

Can't say about them other than their burst rates under Linux are slightly
faster than the Intel EtherExpress Pro but their average throughput is
lower.
