I have a G41, gentoo-sources-2.6.12-r6, with trackpoint-2.6.12.patch
applied.
# ls /sys/devices/platform/i8042/serio0
bind_mode  description  driver  ext_dev  inertia  middle_btn_disable
power            rate   resetafter  sensitivity  speed   transparent  ztime
bus        draghys      drvctl  id       jenks    mindrag
press_to_select  reach  resolution  skipback     thresh  upthresh
# ls /sys/devices/platform/i8042/serio1
bind_mode  bus  description  driver  drvctl  extra  id  power  scroll
set  softraw  softrepeat
# cat /sys/devices/platform/i8042/serio0/description
i8042 Aux Port
#  cat /sys/devices/platform/i8042/serio1/description
i8042 Kbd Port

However, in /var/log/messages, I have
kernel: serio: i8042 AUX port at 0x60,0x64 irq 12
kernel: serio: i8042 KBD port at 0x60,0x64 irq 1
kernel: mice: PS/2 mouse device common for all mice
kernel: input: AT Translated Set 2 keyboard on isa0060/serio0
kernel: IBM TrackPoint firmware: 0x0E
kernel: input: TrackPoint IBM TrackPoint on isa0060/serio1

It looks as though there's some confusion between the keyboard and the
trackpoint.
