natsemi in rck-sources

[xiao]

Here rck-sources refers to the kernel source patched by
Rhino.
Whe I boot the rck-sources kernel on a Athlon xp box, my netgear FA311 ethernet card failed to
work although the "natsemi" module was loaded. I tried to compile the kernel and the modules
under several different CPU archetecture settings, the card still refuse to work.

However, on my modified vanilla 2.4.20 kernel which was patched with low latency, preemptive,
ext3 patches, the ethernet card works very well.

If I recalled correctly, this natsemi problem also was shown for CK_sources kernel.

In all, as I know, some kernel sources including development source kernel do have
this notorious "natsemi" problem.

Anyway, It is neccessary to identify which patch causes this problem.
Can anyone give me a hint to solve this problem?
Thanks a lot.
