I saw the EDD support in the code of lilo v22. It was once introduced
in unstable potato, and then retracted because the problem that it can
not boot up Linux 2.2.x on some machines. I have not seen those problems
on my system, and keep using that by holding lilo package.
$ dpkg -l |grep lilo

the sample code of extipl claims that it can do this also. I test it
on another machine which is on my office (secretly :). And it can boot
the Debian and Win-NT, with simple switching by hitting shift key and
enter the number of the partition at the boot time. I think mbr can
do the same thing.
And I have heard that recent (CVS version) grub can boot up the linux
from > 8GB area. In the changelog, it may be implemented since July or
August in last year.
