I'm using a Thinkpad T43p (2GB memory, 100GB disk) with 3.9-stable.
Speedstep and 'apmd -C' are ok.
Even with 2GB memory, mfs is limited to a bit under 1GB, and process
data size is limited to 1GB, but these are generic OpenBSD i386 limits,
not specific to this hardware.
The builtin bge0 (10/100Mbit ethernet) is 'interesting':
* it works fine when connected to an ethernet *switch* (eg Netgear DS105)
* it works fine when connected to some ethernet *hubs* (eg Netgear DS104)
* it doesn't work at all ("no carrier") when connected to some other
ethernet *hubs*, even ones of the same model (Netgear DS104) which
work fine with other people's Thinkpads.
In the (normal) case when it works fine, I typically get around 8 MB/second
at 60-80% CPU usage for scp of large files to/from nearby fast machines
over a 100Mbit switched network.
The builtin ath0 (wavelan) works fine.
USB flash disks work fine with either 'mount -t msdos' or mtools.
I haven't tried any pcmcia cards. I haven't tried audio.
X.org is beautiful at 1600x1200 pixels, but it doesn't recognize
the middle mouse button. :(
Suspend to ram (= Fn-F4) works fine, although the builtin bge0 network
port looses its state (needs 'sh /etc/netstart' to get it going again).
The main thing I've found which doesn't work at all well is sending video
to the external video connector to drive a projector for conference
presentations. The usual tricks like changing the X resolution (with
'xrandr') and toggling Fn-F7 have no effect whatsoever -- so far as I
can tell there's no signal at all going to the external video connector.
The only way I have found to make this work is to reboot, enter the
IBM BIOS setup, and set the 'boot video device' to 'LCD + VGA' (instead
of the default 'Thinkpad LCD'). The machine then boots normally (with
the console display), but when I start X the builtin display is blank
and 1280x1024 video is sent to the external connector. My usual
'xterm -fn 7x14 -fg white -bg black' is really ugly in this video mode,
but 'xpdf -fullscreen' looks fine.
ciao,
