2.6.10-rc2-bk17: still oopsing with 'modprobe -r dvb-bt8xx'

[Eyal Lebedinsky]

The first command after a single-user boot.
.config and boot log (ttyS0) attached.

There are too many components involved so I am not emailing specific
maintainers. If someone feels like owning this problem then let me know
and I will CC you in the future.
