On sparc:
morninglightmountain# uname -pr
8.0-CURRENT sparc64
morninglightmountain# ls /boot/kernel | wc
853 853 13045
morninglightmountain# wc -l /usr/src/sys/sparc64/conf/GENERIC /usr/src/sys/amd64/conf/GENERIC
247 /usr/src/sys/sparc64/conf/GENERIC
322 /usr/src/sys/amd64/conf/GENERIC
569 total
So, fewer drivers and also less devices in GENERIC, as might be expected.
regards,
Ruben
