> Are these -current kernels, including Scott Reynolds' patch to delay()?

Yes.
I uploaded another kernel last night that seems to work for Matías.
It's under the same name and is dated Jun 29 04:54 (that's GMT ;-).
Can you try that one, Guy?  I had the delay() in adb_reinit tuned up to
4000, with it back to 3000 (a change I missed when reviewing the diffs),
things seem to be better for the Q650.  My Q700 couldn't care less...
