Description of problem:
During boot-up, if lilo's vga=8, then the text console is as it should be: 132x43. At a certain point, the characters become larger
and the lines reduce to 25 or so. This happened with two separate systems, with both S3 and Trident PCI cards.
Commenting out the "# Load system font" section of /etc/rc.d/rc.sysinit solves the problem.
After booting successfully with this commented out, simply running "setsysfont" changes the console to 25 lines again.
Steps to Reproduce:
1. Set "vga=8" (or whatever) in /etc/lilo.conf, run lilo and reboot. Note it starts with 43 lines and goes to 25 lines at a certain point
during boot up.
2. Comment out the "# Load system font" section of /etc/rc.d/rc.sysinit and reboot. Problem does not occur.
