Pau already knows this from previous E-mails, but others may not, so...
I have a more favorable experience to report, albeit on a T41p:
With 4.2 (both -release and now -stable), suspend works perfectly.
[Under 4.1 suspend would hang the system unless I switched to the
'vesa' Xorg driver; this was workable, but meant I lost any hardware
video acceleration.]
Some details:
IBM/Lenovo ThinkPad T41p, model 2373-221
I have *only) OpenBSD on the disk, with no DOS or IBM "recovery partition"
(I wiped the latter to give more space for OpenBSD)
Suspend works fine via either Fn-F4 or 'zzz', under console or under X.
X autoconfigures (I do *not* have an /etc/X11/xorg.conf) to 1400x1050
pixels, with at least some of the hardware video acceleration working
(eg XVideo extension works)
X restores the screen display fine after a suspend/resume cycle.
A suspend/resume cycle kills all active network connections, but
'sh /etc/netstart' restores things fine.
There's no disk partition to hold suspend info, and removing power when
in the suspend state kills the suspend (i.e. when power is restored I
have to do a cold reboot with full fsck etc). So, I conclude I must be
doing suspend-to-RAM. Power consumption in that state is very low (I
can only give an upper bound and say it's less than a few percent of a
full battery per day), so this is fine for me.
