Hello Joerg,

  JN> I have an ASUS A8V board...

Two friends, whose opinions I value, have those and swear by
them.  The only thing that puts me off slightly is lack of a
PCIe slot.  Neither of those friends runs NetBSD at present,
so your dmesg output is very welcome!

Perhaps you hit the LBA28 "137 Gbyte" wall?
