On our X61s's setting 'debug.acpi.disabled="hostres"' does not change 
the inability to boot 9-BETA1, 9-RC1 or -current.

What does fix it however, is to change the Kingston SSD drive to a 
standard mechanical one. This is verified on three different X61s's, see

http://www.freebsd.org/cgi/query-pr.cgi?pr=amd64/170487

Is there something else I could try or should I just switch drive and be 
fine with it?

I'm happy to try anything you suggest.

Thanks,
