Well, i got the (lenovo|ibm) Thinkpad z60m last week, had some time to
play with it, finished transferring my data from the Toshiba Tecra A2
to it and tweaking it a bit. for those who care, it's the 253044M
model, with the titanium cover.

Actually, it's  an if_iwi - works out of the box, no problems thus far.

Yup, cannot resume (well, CAN but cannot use the laptop
afterwards :-D ) if suspending FROM the virtual console used by X if I
have DRI enabled. I removed the DRI option from xorg.conf and:
 - I can resume with no other problem than some desktop
background corruption (XFCE4.2.3.1) , which is fixed by issuing a
xfdesktop -reload. 
 - radeon.ko and drm.ko are NOT loaded ( I still need to understand the
difference between drm and dri...)
 - graphics perfomance has dropped (As expected), from about 750+ in
glxgears to 220 approx.

If I really need DRI, the alternative would be to switch to text
console before suspending - i'm pretty sure it works fine in this case.

Also, in the Toshiba, I had to set this knob :

hw.syscons.sc_no_suspend_vtswitch

to 1. This makes bad things happen on the z60m, so it's back to 0.

Powerd seems to be working fine too.

thanks for this, i;ll give it a try soon.

yup, all fine there.

Also, I had to remove 
device apic

from my kernel config - else resume would fail in every single case
(text mode so I would assume DRI has nothing to do).

About to try to OSS sound drivers. 

- The fingerprint scanner is detected but i doubt it'll be useful (definitely not enabling the bios option to rely on the info stored in this little device for booting up :) )

- Bluetooth comes up as ugen0, and it gets switched on/off with Fn-F5, whilst both wifi and b-tooth are affected by the physical switch at the front of the laptop.

IRDA is detected but i havent played with it yet.

Battery life : i havent had much chance to test it yet, but it seems to hover around the 4 1/2 hours at 95%... not sure how it'll perform under normal use yet.


If anyone wants any other info, just ask away :)

thanks for all your suggestions / comments

Best,
Beto
