The problem seems to be fixed in -current.  Based on the hint by Manuel
Bouyer, I've backported the fix to the 1.5.x release branch and submitted a
pullup request for NetBSD 1.5.3.  In the meantime, I've attached the patch
relative to 1.5.2 and the resulting dmesg for my Dell PowerEdge 1550.  Note
that the dual AIC-7899 adapters both attach correctly now.

	Cheers,
