8.2-STABLE configured with:
#device ehci
#device ohci
#device ohci
in my kernel config.
{ehci,ohci,uhci}_load="YES" in loader.conf

the same symptoms are for 9.0-BETA2 (official memstick)

My laptop is able to beep - echo -e "\007" does a short beep, but there is no
beep on resume.

I did the following:

boot -s (all modules)

kldunload ehci
kldunload ohci
kldunload uhci
kldunload firewire
kldunload nvidia
sysctl hw.acpi.verbose=1
sysctl debug.acpi.resume_beep=1
sysctl hw.syscons.sc_no_suspend_vtswitch=1 (also tried without it)
zzz
(had to press Ctrl-C to go to sleep)
press power button
- cpu fan goes on, screen is blank, no beep
- wait for 3 minutes, nothing changed

next I tried:
- at bootloader: unload, load /boot/kernel/kernel, load
/boot/kernel/{ahci.ko,zfs.ko}
- boot -s
- all sysctl's as above
- zzz (no Ctrl-C needed)
- pressed power button for resume
- nothing happens - no beep, no resume, screen is blank

so ehci,ohci are not the problem here.

This laptop has: 
- core i7 processor
- nvidia card (tried to suspend&resume without nvidia.ko, no luck)
- encrypted hard drive (tried to suspend&resume without it, still no luck)

best regards,
