3c905B fast on NT, slow on Linux

[Roger Ward]

try loading the driver as a module, and manually setting the options flag
(refer to the doc. w/ the vortex drivers, etc... don't happen to know the
flags at the moment)

a similar problem existed on my computer, and manually setting the options
(instead of auto/negotiate/select) worked much better... 

hope this helps,
