After building 2.5.51 I am still unable to unable to load and configure
drivers for an eth0 wireless interface on my Presario 12XL325 laptop. 
The
SMC2632W card works on all 2.4 kernels and 2.5 kernels through  2.5.47
as
previously documented in messages to this list.  Nothing after 47 will
load and configure the eth0 device.

Mindful of the unsettled nature of module loading in latter 2.5
versions,
I do a build with modular components and a build with everything built
in.
Rusty Russell's latest module init tools work well with both 2.4 and 2.5
kernels, so I'm skeptical that module loading problems are the cause of
my
problem.

I've included a copy of my dmesg output, together with /proc/interrupts,
and /proc/ioports for the run in question.  The output shows orinoco_cs
does a RequestIRQ and gets a resource in use messsage.  Running the
dhclient program gives an eth0; no such device message.
