I see.. I noticed I was pretty stupid with my hook, I forgot
what I'd read/skimmed in the documentation. I got it working,
per se, but it didn't do what I wanted to ;)

Isn't raidtab 2.4 technology? iirc 2.6 doesn't use it anymore,
and thus it's redundant for me, as I run 2.6.*-ck kernels...

I will look into that and tell how it went.

Now the host machine is in a somewhat broken state; the disks
are 200GB RAID1 and the BIOS LBA is only 28-bit, so I can't
boot it directly.

Stupid of me not to test-boot it (it must be booted with pxe)
after the RAID become operational, but I will fix it today.
