It means that Kernel and BIOS each invent a fake geometry for your disk,
and they did not invent the same fake geometry.

No.
Linux does not use the BIOS, and does not use CHS either, so geometry is
totally and completely irrelevant to Linux.
Depending on the precise LILO version, and on whether you give options
like "linear" and "lba32", LILO might or might not be confused.
Test whether you can boot. If booting works all is well. If not
make sure you set at least one of "linear" and "lba32".
If you also have DOS on the same disk the story is more complicated.
All systems on a disk must agree as to where the partitions are,
or corruption will be the result.
