Testing with the old one (the > one that was very unstable) now - will report back tonight. I just tried to build a kernel with one restricted to 1000, but quickly got a build failure. It might be caused by having tried to build a kernel using a 1200 previously and the device still being a bit messed up from that, though.
I should give it some rest and try again in a few hours. -- Julian Andres Klode - Debian Developer, Ubuntu Member See http://wiki.debian.org/JulianAndresKlode and http://jak-linux.org/.
