[ubuntu-nz] Last kernel upgrade broke my wireless

[Tim Uckun]

Yesterday I ran the update but when it asked me whether I wanted to
keep my /boot/grub/menu.lst or use the one in the update I said to
keep mine. The reason I did this is because I have a kernel option I
pass in in order to make sure my keyboard works on startup
(i8042.reset).

Well now the wireless driver is not loaded.  The "enable wireless"
option is disabled.

I tried loading the module with modprobe iwl3945 and nothing seems to
happen all I get is the following warnings.

WARNING: All config files need .conf: /etc/modprobe.d/TIM_IWLAGN, it
will be ignored in a future release.
WARNING: All config files need .conf:
/etc/modprobe.d/TIM_SND_HDA_INTEL, it will be ignored in a future
release.

That's fine, I don't really use those options anymore anyway and all
the entries in those files are commented out.

I modified the menu.lst to point to the latest kernel and rebooted but
no joy in that either.

I tried dpkg --configure linux-generic but it refuses to configure it
and I can't figure out a way to force it.

How do I tell ubuntu to re-install the kernel and put in whatever
menu.lst it wants?
