I'd suggest talking to:
NETWORK DEVICE DRIVERS
P: Andrew Morton
M: akpm at digeo.com
P: Jeff Garzik
M: jgarzik at pobox.com
L: linux-net at vger.kernel.org
specifically, as they probably know what changed in terms of network
code in between 2.5.30 and 2.5.46 and might even be able to give you
diffs to apply to 2.6.0-testCurrent.
