Bug#358816: Loading snd-powermac causes an oops

Matthew Kraai
Package: linux-image-2.6.16-1-powerpc
Version: 2.6.16-2

When I run "modprobe snd-powermac" on my iBook, the kernel generates
an oops:

> Unable to handle kernel paging request for data at address 0x00000002

Version: 2.6.17-2

This problem is fixed in 2.6.17-2.  I am able to load snd-powermac and
a grep through the kernel source reveals no module requests for
i2c-keywest.

It may have been fixed in an earlier version, if anyone cares to
check.
