With KMS I could run with VESA and without it I needed to pull VESA from my kernel. As of today I am running fine with KMS, i915, and vt(4) with a standard GENERIC 10-STABLE kernel. I was running KMS and vt(4) well before they were MFCed, so I don't remember when I stopped adding "nooptions VESA", but I definitely used to need it to make suspect/resume work and don't any longer. In any case, trying kernel without VESA is a good idea. -- Kevin Oberman, Network Engineer, Retired E-mail: rkoberman@gmail.com
