It seems to me that at least with my ThinkPad R60 and the newest Ubuntu Edgy kernel (2.6.17-11) I'm better off not using the ec_intr=0 parameter at all. Cause suspend to RAM seems to work with the default kernel parameters, but stops working with ec_intr=0. (I just figured this out, so I'll let you know if suspend to RAM starts turning evil on me again. But for now it seems to work repeatedly...)
