Warner,

My laptop has <TI1225 PCI-CardBus Bridge>
I have been googling and have seen other problems related to this cardbus
in freebsd.
I think possible this "alignment" problem is related to this specific
cardbus chipset. I will review the pccbb code but I'm not an expert into
this.

On the other hand, could someone commit this for rman? It's a clear
mistake:

 		} while ((rstart & amask) != 0 && rstart < end &&

+		rend = ulmin(s->r_end, ulmax(rstart + count - 1, end));
 		if (rstart > rend) {
 			DPRINTF(("adjusted start exceeds end\n"));
 			continue;
