I have a Thinkpad W510 with nvidia driver 260.19.26 from xswat, running in amd64 maverick, stock 2.6.35-23 kernel. Whenever I resumed from suspend, I mostly noticed the graphics slowdown while (smooth) scrolling a PDF in evince. A reboot restored graphics performance. After reading this, as well as seemingly duplicate bug #671932, I went and disabled hyperthreading in the BIOS. Voila, no more slowdowns after resume! Haven't tried the 2.6.36 kernel yet (not too sure how) to confirm Claudio Melis's comment that disabling hyperthreading is no longer needed with that kernel.
