Actually, while FreeBSD claims it's a 372N, both NetBSD and OpenBSD
agree it's a 372A.  Also, FreeBSD reports UDMA133, instead of SATA150
like my onboard sata ports.  Is this chip a modified PATA driver?  There
seem to be lots of references to IDE drives used with this chip.

On a vanilla 2.6.13.2 kernel, the FREQ is 144 and the PLL is 66.  The
driver still seg faults when it fails to find a stable clock.  I can
probably post an updated patch that will at least prevent it from
crashing and fail properly instead.  The full dmesg of the driver
insertion is below.
