I can't remind where original discussion held (on mobile@ ?), building
kernel with

  options  SC_NO_SUSPEND_VTYSWITCH

or adding following line into /boot/device.hints

  hw.syscons.sc_no_suspend_vtswitch=1

may help.  See syscons(4) for details.

Try

  # sysctl hw.acpi.lid_switch_state=S3

Other issue I noticed is IRQ uchi0 uses now changed when ACPI enabled.
If this is wrong behavior (i.e. APM do the right thing), you can
fix up IRQ routing for ACPI by specifying

  hw.acpi.pci.link.%d.%d.%d.irq="IRQ number"

in /boot/loader.conf.  See acpi(4) for details.

Hope this helps,
