Please could you post the full kernel log so I can confirm.

It does not seem to be trying to insert the module itself; and if I try using depmod/modprobe, then I get the error mentioned in the initial report.

I guess the installer udebs will be rebuilt at some point against the
newer kernel.

Thanks. It's not an emergency anyway, as most of the domU's I need will be running Lenny.

Regards,
Emmanuel.
