I studied the NetBSD viaide driver for a while and even tried changing 
the code a little bit (skip checking for BSY flag for example) and it 
still didn't work.  The reset failed.  The BSY flag never cleared.  
Something just didn't seem right, so I looked at FreeBSD's code, but it 
looks totally different because of the CAM sub-system that they use now.  
I wasn't certain if it was NetBSD's viaide or the wdc driver at fault, 
but then I had an idea to disable viaide and let the pciide driver take 
over, and it works!  wd0 was found right away and I've installed the 
system now.  Does that mean that wdc probably isn't at fault and I 
should focus on the viaide driver?
