Yes, its loaded:
lsmod | grep -E "(acpi|think)"
acpi_cpufreq           10796  2
freq_table              5536  3 acpi_cpufreq,cpufreq_stats,cpufreq_ondemand
thinkpad_ec             8464  1 hdaps_ec
thinkpad_acpi          51836  0
nvram                   9992  2 thinkpad_acpi
pata_acpi               8320  0
libata                159344  4 pata_acpi,ata_piix,ahci,ata_generic
processor              37384  4 acpi_cpufreq,thermal

Currently my display brightness OSD seems to work fine, as it keeps 
state correctly.

I'm only looking where I can make sure that pressing "volume down" 
button will actually unmute the sound, as "volume up" button already does.
