Patch from Woody Suwalski:

Erik, I think we have met online some time ago when I was in Corel/Rebel
    Netwinder project....

Anyway, I would like to use BB on 2.6.0 initrd. 1.00-pre4 works OK, if
insmod is actually presented with a full path to the module. Otherwise -
problems (not to mention conflicts when 2.4 modutil is enabled)

Here are some patches for insmod and modprobe which try to walk around
the default ".o" module format for 2.2/2.4 modules (you have probably
noticed it is now .ko in 2.6 ;-)) Trying to steal as little space as
possible if 2.6 not enabled...

The modprobe is still not perfect on 2.6 - seems to be jamming on some
dependencies, but works with some (to be debugged). Anyway after the
patches it at least tries to work....

Will there be a 1.00-pre5 coming any time soon?

Thanks, Woody
