My problem was a bug in LILO. The kernel + initrd image for Linux >=
2.6.26 was too large. Adding the option "large-memory" in
/etc/lilo.conf solved the problem.
See Debian bug #479607 for example. The option "large-memory" is now
set by default in new Debian lenny installations.

I could not make grub2 from an USB memory stick to work. The boot
partition on the USB memory is seen by rEFIt but it looks like the
firmware can't load it.
