Bigger disks should Just Work(tm) as long as kernel and loader are  
within the range that the firmware can see.

For example:
wd1 at atabus0 drive 1: <ST3160023A>
wd1: quirks 2<FORCE_LBA48>
wd1: drive supports 16-sector PIO transfers, LBA48 addressing
wd1: 149 GB, 310101 cyl, 16 head, 63 sec, 512 bytes/sect x 312581808  
sectors
wd1: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 5 (Ultra/100)

This is from a PowerMac G4, the firmware and MacOS X see only 128GB  
which doesn't keep NetBSD from using the whole disk.

have fun
