I am tracking Squeeze and yesterday installed linux-image-2.6.32-5-686-bigmem version 2.6.32-19 from Sid on a Lenovo ThinkPad X201 with the identical video chipset as listed by Andrew in #585910 - so far, version 2.6.32-19 is working well for me and I thought I would pass along my success. -- Kind regards, Michael
