linksys PNIC card hangs up under load (v. 0.91g)

[Scott Kidder]

Hi Eric,
I have that same card and have spent the last week wrestling with it to get 
it working under Linux.  Under the advice from Linksys' Linux Support page, 
I attempted using the latest Tulip driver (v0.91g) but had no luck.  Only 
when I tried the *modified* tulip driver included on the second disk 
included with the card did I have any luck.  I think that it's v0.89, and 
works pretty decent.
