the boot manager is probably your problem. i know a situation with the
nt-bootmanager: it does not use the real boot sector to boot a partition,
but a copy stored in a file. thus, if you recompile your kernel and
re-run lilo, lilo will update the real boot sector, but the boot manager
will not realize it and will still run the old code stored in the
image-file. the old code of course has an invalid (old) map ...

the solution (for nt - i don't know bootmagic):

dd if=/dev/sda2 of=/c/bootsek.lin count=1

where /c is the mount-point of a fat-partition, where the nt-bootloader
resides. bootsek.lin is an arbitrary name choosen for the image file (you
would have to use the one, that already exists).

i hope, that this technique is also true for bootmagic.
good luck!

PS (to everybody): *please* make line-breaks ... it makes quoting so much
easier ...
