Unfortunately not. I have been thinking lately that I should upgrade to a new kernel - but I don't get around to it very often. So this is probably a good opportunity to do so. > If not, fixing it is quite trivially easy: Get a copy of any recent liveCD or > rescue image that you can boot, and boot into it.

I built it earlier, but for some reason grub won't boot it - perhaps b/c I gzip compress the kernel (kernel option)? Not sure. Going to figure it out though. Right now, I'm using a vintage 2007 live CD; but chrooting over to the partitions on the hard drive. I don't have network since it won't recognize the firmware needed for my wireless (b43legacy driver). Perhaps I'll try a newer image... > btw, this is exactly the reason why user-oriented distros like Ubuntu mount > system partitions using the fs GUID, not the kernel device name.
