I suspect -mobile might be the best list for this one, perhaps -acpi 
but that's usually more about development than usage.  You might try 
searching the archives of either for mention of the X40.

My T23 requires hw.syscons.sc_no_suspend_vtswitch=1 to suspend/resume 
cleanly (7.0), so does my old Compaq Armada (but that's APM, not ACPI)

That might be one to try either way, with other combinations.

I've found that vesa_load="YES" helps on my T23 especially if suspending 
from a VT rather than in X, referring to your 'console comes up blank.' 
Something to try anyway, and I don't think it ever hurts.

If hw.syscons.sc_no_suspend_vtswitch=1 is no help, I'd try -mobile ..
