I own a IBM Thinkpad X24 (2662-MQG, 640 MB RAM) with UltraBase X2.

FreeBSD on the X24

add to /etc/rc.conf:

#enable automatic power-management with EIST (full speed on AC, load-dependent clock speed reduction on battery)
powerd_enable="YES"
powerd_flags="-a max -b adaptive"

add to /etc/sysctl.conf:

#place lower cpu clock speed limit for better responsiveness (powerd/cpufreq pm)
debug.cpufreq.lowest=549
#make use of deep sleep CPU power state (reduced core voltage for even more power saving)
hw.acpi.cpu.cx_lowest=C2

add to /boot/loader.conf:

#wlan-card and wpa-support for atheros-based 802.11-wlan cards
if_ath_load="YES"
wlan_tkip_load="YES"
wlan_wep_load="YES"
wlan_xauth_load="YES"

#power management support
cpufreq_load="YES"
#deep sleep support
hw.acpi.cpu.cx_lowest="C2"

#support for ibm-extras and smbus-controller
acpi_ibm_load="YES"
ichsmb_load="YES"
