Really? The Alpha has about twice as much MHz, but the 21064 is known to
need a lot of MHz per MIPS.

Yes. The dz(4) probe routine in NetBSD prior to 1.6 (1.5?) modified some
bytes in the FLASH ROM of the VS4k9x. This causes a FLASH checksum error
at startup und thus preventing autoboot but everything else works. It is
save to use 1.6 and there is a MOPable FLASH ROM update for the VS4k9x
available that repairs this.
