I'm aware the s3fb driver has big endian issues, I can help fix those
issues so I can get the card working. Or in other words, I'd welcome
advice on how to proceed with this.

It's not endian issues, this driver has other problems.

It uses the VGA register accessors with a NULL regbase, which is not
going to work on sparc64.

It needs to access the VGA register space relative to the I/O space
of the PCI controller domain it is behind.

Probably if you replace the NULL values passes to vga_r*() and
vga_w*() with the I/O space resource base of the chip (should be
resource "1") it might work.

Probably s3fb also relies on a card having been initialized by the VGA BIOS.
