I had similar experiences on a mobo with an 8GB limit.

The one thing to watch out for is that back when I tried it, LILO would
only boot if the superblock of the relevant partition was within the
size the BIOS can see. So I had a 7.9GB windows partition and then my
root partition. The superblock of root was within the range required so
it worked fine. Once linux boots it totally ignores the BIOS.

I agree.
