>Description:
Prior to version 1.35 of viaide.c, if I added entries for device ID 0x0591 in pcidevs.h, viaide.c, et. al., I could use both of my SATA drives.

Presently, I am able to use viaide0:0, but I get this in dmesg now:

wd0 at atabus0 drive 0viaide0: port 1: device connected, but communication not established

Note how there's no \n after the wd0 line.  I also repeatedly get a lot of messages like this (with atadebug_mask=0xffff):

>How-To-Repeat:
Attempt to use NetBSD-current on an Asus P5VDC-X motherboard with two SATA devices connected.
>Fix:
I do not have enough familiarity with this to figure out anything aside from backing out to 1.34 of viaide.c and adding the VT8237A entry manually.

NOTE: I have tried swapping SATA devices (both Western Digital WD800J drives) to rule out a device problem; it made no difference.
