The bad things I've read are all regarding the first generation
SIL chips with FreeBSD.  They work fine with NetBSD (and other OSes)
so the problem is with the FreeBSD device driver.  I haven't seen
anything (pro or con) about the 2nd generation chips e.g. Sil 3124
with FreeBSD.  The 2nd gen chips are supposed to be much better and
faster than the 1st gen chips.  Does anyone have experience to report
with the Sil 3124 (PCI), Sil 3132 (PCIe) or other 2nd generation Sil
chip with FreeBSD?

This may depend on the firmware on the mainboard?
