Hi Sean,

Thanks for the pointer, unfortunately both of those bugs were fixed in 2008 as:
6645543 relax AHCI checks violated by JMicron JMB363 controller
6648246 AHCI driver looks for its registers wrongly, blocking support
for JMicron JMB363

This is not the first time problems have been mentioned for JMB363
controllers recently, though.

If you're interested in looking into this problem, you should sign up
on the illumos developer mailing list.
