Hi!
So I have this netbook with a small screen (10 inch 1024x600)...
I have toyed with a custom kernel using an alternative font for the
wscons framebuffer console to get bigger screen estate.

While experimenting, I've found that fonts with WSDISPLAY_FONTENC_ISO
encoding like bold8x16-iso1 or sony8x16 are ok, while fonts with
WSDISPLAY_FONTENC_IBM (bold8x16, vt220l8x8) cause the kernel panic
below:

I'm very happy with FONT_BOLD8x16_ISO1, I just wanted to report
what I've found.
Ciao,
