Those lines can be ignored. The driver normally uses VBE calls to save/restore the initial state. There's a bug in that save/restore mechanism with many 845G BIOSes, so to work around this, it just saves the original mode number, and calls the BIOS to re-program that mode at exit/VT switch. This is setting it to the initial 132x60 state, not the state after your setfont call. If you can to identify what parameters setfont is changing, it would be possible to modify the driver to save/restore them. I haven't looked into what mechanism setfont uses to change the character size.
