Summary:                    [PATCH] on-demand module loading fails with 2.6.X
Description: 
Kernel modules autoloading doesn't work with BusyBox and
kernel 2.6.X. This feature is useful to load modules on-demand, to
minimise kernel memory footprint and power consumption.

If you have configure properly /etc/modprobes.conf, a simple "ifconfig
eth0" will load the appropriate network driver. Kernel calls modprobe,
which does the insmod.

The fix is pretty safe, when calling insmod for 2.6.X kernel, we don't
pass offending parameters. Note that in the BusyBox context, a lot of
those flags don't make sense and just add bloat, so I would not really
recommend implementing them.

Patch is attached. I made the patch for busybox-1.00 and fully tested
there, but I've verified that it applies smoothly and compile with the
02-june-05 snapshot.
