Does 10.1 with vt in text mode support _all_ the following in rc.conf?

scrnmap="koi8-u2cp866u"
font8x16="cp866u-8x16"
allscreens_flags="80x30"
keymap="ru.koi8-r"

One of my workstations uses nvidia-driver-304-304.88_2
(the latest nvidia-driver 331.67 doesn't support my videochip),
another xf86-video-vesa-2.3.3_4 (RC410 [Radeon Xpress 200/1100], 1280x1024).
I use both X and virtual terminals.
Locale: lang=ru_RU.KOI8-R
What problems will I have without sc?
