interaction between i915/radeon"

I agree - I did some more testing and placed an entry for the radeon-
module into /etc/initramfs-tools/modules, and voilá - no crash! (after
booting into X I can't get back to the text-console, but that's possibly
another issue).

What proves the "bad interaction" even more is: when also placing "i915"
into /etc/initramfs-tools/modules BEFORE "radeon", booting isn't
possible at all any more, but when placing i915 AFTER radeon, booting is
possible, but I got a black screen (as in totally black, that is: no
backlight) until X starts up.

I'll try to get logs of four different initrd-configurations (though I
doubt I'll be able to record the one where the crash occurs already
during running of initrd...)


P.S. off-topic, I knew a cjwatson once - hi Kamion ;-)
