vt console driver

from the wiki:

Video driver loaded at boot time

Radeon

The Radeon driver loads one or more firmwares when initializing the
card. If you want to load radeonkms from loader, you must include the
firmwares too, because automatic loading won't work (the filesystem
isn't mounted at the time of the card initialization).

To list the firmwares required by your card, "kldload" radeonkms and
look at the loaded modules. Here's an example:

$ kldstat | grep radeonkmsfw
19    1 0xffffffff81fc0000 189d     radeonkmsfw_JUNIPER_pfp.ko
20    1 0xffffffff81fc2000 1ca6     radeonkmsfw_JUNIPER_me.ko
21    1 0xffffffff81fc4000 1325     radeonkmsfw_JUNIPER_rlc.ko

In this case, one would need to build into/load:

radeonkmsfw_JUNIPER_pfp
radeonkmsfw_JUNIPER_me
radeonkmsfw_JUNIPER_rlc
