Uhm, unfortunately, that doesn’t work, and I actually don’t think this is 
possible. I took a look at the code, and it seems the file in which parsing of 
boot.cfg is done is sys/lib/libsa/bootcfg.c.

In this file, only “menu”, “banner”, “timeout”, “default”, “consdev”, “root”,
“format” and “clear” are recognized. Unknown commands are handled by a function 
given as argument. On i386, this command is defined in 
sys/arch/i386/stand/lib/bootmenu.c and implements the additional “dev”, “fs”, 
“load”, “rndseed” and “userconf” commands. Nowhere is “gop” or “text” 
implemented in boot.cfg, or if it is I couldn’t find it and it doesn’t seem to 
have any effect on my computer. ^^’

This does work. So while my bootloader menu is unreadable, at least netbsd is 
booted with decent display settings. :D
