My nc6220 loses all its ATA devices on resume.  Mine also has a serial console 
so I've been able to debug some.  Try 
http://www.FreeBSD.org/~jhb/patches/ata_reinit.patch (fixes a panic on 
resume) and http://www.FreeBSD.org/~jhb/patches/ata_resume.patch (doesn't 
lose ATA devices on resume).  This gets it closer, but somehow resume is 
hanging elsewhere as i still don't get to where I can hit enter on the 
(serial) console after this.  I have verified that you can use acpi_video to 
turn the LCD on and off, so that will be useful once it gets far enough to 
run commands during resume.  On my laptop at least, though, acpi_video always 
thinks all the output devices are off even when they are on.
