Access to swap is entirely a Linux not BIOS matter so it conforms to
Linux not BIOS restrictions. In other worsds there is no 1024 limit
for swap.
There are there three things who must conformd to BIOS restrictions:
the boot loader, the kernel and initrd. However the GRUB boot loader
seems to be abe to can access kernels and in initrds who are beyond
the 1024 cylinder or in the second IDE controller. Perhaps modern
BIOSSes don't have those stringent limits.
