Lookie, lookie:

Device (PS2K)
{
Name (_HID, EisaId ("PNP0303"))
Name (_CID, EisaId ("PNP030B"))
Method (_STA, 0, NotSerialized)
{
ShiftLeft (One, 0x0A, Local0)
If (And (IOST, Local0))
{
Return (0x0F)
}

Return (Zero)
}
...

Device (PS2M)
{
Name (_HID, EisaId ("PNP0F03"))
Name (_CID, EisaId ("PNP0F13"))
Method (_STA, 0, NotSerialized)
{

But I guess because there are no devices plugged in ACPI they are "inactive"
and thus ACPI drop them. I was always wondered by ACPI did that. Len?
