With a CRT connected to such a device, I get a white screen with 
(according to the monitor) a vertical refresh frequency of 45Hz 
(horizontal 36kHz). The logfile says avivo was trying to do 1152x768.

This broke the console, but maybe I used a different mode than the 
console was in.

Change the pio address to what? I tried with 0xde00, the location of the 
I/O ports according to lspci -v. This produced:
         tmp = INREG(0x0000003C);        /* should get 0x00010000 */
         tmp = INREG(0x00000000);        /* should get 0x00005010 */
         tmp = INREG(0x0000003C);        /* should get 0x00010000 */
         tmp = INREG(0x00005054);        /* should get 0x00000000 */
         tmp = INREG(0x0000003C);        /* should get 0x00010000 */
error ill formated line:
line(13):"VBE Version 3.0"
