Here is my 2c add...
I finally managed to compile a tulip.o version under my (pretty-standard) 
Mandrake 8.0. The module compiles right, and the hardware is recognized... 
and it seems to correctly work. But after a given time, the network adapter 
starts dropping _lots_ of packets.... making it impossible to use the network 
(I was testing it between a direct connected cable, using both ftp and 
telnet).
At the same time, I got a lot of "Warning kfree_skb" messages on the kernel 
log (dmesg...), but (luckly) I didn't get any file corruption...
Since then, I stopped using the ethernet... and I'll be waiting until a new 
release is out (thanks Alan, you are doing a great job, as usual!)
