HP EliteBook 8460p uses it for sure! Here are DSDT snips:
Method (\_SB.PCI0.LPCB.SMAB, 3, Serialized)
{
If (LEqual (And (Arg0, 0x01), 0x00))
{
Store (0x01, Local0)
Store (\_SB.PCI0.SBUS.SWRB (Arg0, Arg1, Arg2), Local1)
If (Local1)
{
Store (0x00, Local0)
}
}
Else
{
Store (\_SB.PCI0.SBUS.SRDB (Arg0, Arg1), Local0)
}
Return (Local0)
}
...
Method (ALRD, 1, Serialized)
{
Store (\_SB.PCI0.LPCB.SMAB (0x33, Arg0, 0x00), Local0)
Return (Local0)
}
Method (ALWR, 2, Serialized)
{
Store (\_SB.PCI0.LPCB.SMAB (0x32, Arg0, Arg1), Local0)
Return (Local0)
}
And ALRD and ALWR methods are used by hp_accel.ko kernel driver.
