Hi, thanks for reporting!

Do you have vesa(4) in your kernel?  It seems dev/fv/vesa.c:vesa_bios_post()
restore the mode when resuming, but it's maybe incomplete in some cases...
I think great work was done in this area, and we can improve this more.

How about switching vty to other different mode vty and switching back
in order to force changing video mode?
I think it's better than re-run vidcontrol.

This is my pleasure :)

Thanks!
