Well with hw.acpi.verbose=1 the messages look like this:

here is the output of "dmesg | egrep acpi_ec0\|EC\ Wait"

acpi_ec0: <embedded controller> port 0x66,0x62 on acpi0

I set hw.acpi.ec.burst_mode=0 in loader.conf but when i was trying to 
chek if it was set to 0 with sysctl hw.acpi.ec.burst_mode i got :

flo at lappi [~] 15 #sysctl hw.acpi.ec.burst_mode
sysctl: unknown oid 'hw.acpi.ec.burst_mode'

Let me know if i can do something else.
