- Sync whitespace and comments with i386 GENERIC. - Add some commented out NICs from i386 GENERIC. Most of them look like they   would work but I'm not sure if they are endian-clean and can't test. There   was a report that sk(4) works on sparc64 but it doesn't look like it would   because it doesn't use busdma. - Improve some of the descriptions of sparc64 specific devices.
