Bug#258010: cciss install boot loader struggle
merge #258010 #245268
could reproduce that error, neither grub nor lilo installs from d-i.
didn't get grub into a workinsg state from vc2,
but after some manual fiddling lilo went along.
first lilo it didn't install itself as also mentioned in #258010,
but after several retries it did..
error reproduced on a amd64 proliant dl385 with sarge installer.
seems to bit others too:
i'll test newer etch beta as soon as it comes out.
