If you're using menu.lst from fai-bootcd then make sure that your
kernel exists and there is a /vmlinuz symlink to it.

If this doesn't work, Grub may be having trouble finding the first (hd0)
drive on your system, could be a chipset/Grub issue.

Grub documentation will explain precisely what this means, failing after
1.5 etc.

Was the kernel definitly built with `make-kpkg`, i.e. a Debian compliant
kernel-image package?

This is the problem then, in Grub (hd0,1) means the second partition
of the first disk - i.e. your swap space.  Try (hd0,0) instead, or
consider creating your swap space as the first partition (apparently
first partition is closest to the centre of the platter and so could
result in the lowest seek times (but this may be wrong, never confirmed
it one way or the other), also makes it easier for sfdisk in FAI
to allocate the rest of the disk to other partitions regardless of size
- re-use the same disk_config file for multiple classes...)
