The following reply was made to PR kern/9520; it has been noted by GNATS.

Seems to be a lock-up. The system doesn't beep when I type anything. Ctrl-Alt-Del and Alt-F? produce no change in the corrupted display. Now, the machine may not be net dead -- I didn't try telneting in from another box on the net, but the console at least is toast. |I wonder if it is possible to type Alt-F1 to get back to ttyv0... No, sorry. I tried that. |I have some theory and will send you a patch shortly. Thank you.

If 132x60 is not listed, |there is no way to get that mode, I am afraid. It appears that 132x43 is as good as I can get with VESA.
