Solved Upgrading my MacPro 5,1 to FreeBSD 12.1 - video kernel driver

As a reaction to Apple's choosing not to support 'ancient' hardware, and in line with my slow migration to bsdland, I'm upgrading my mid-2010 MacPro (with its 12-2.93GHz cores and a measly 32GB ram) to FreeBSD 12.1. The install went flawlessly. However, when I tried kldload radeonkms or amdgpu , it loaded the tahiti modules, but the result was pathetic, text in the console was very laggy. Without the driver, the console works fine and it expands to take up the entirety of my 30inch hidef monitor. I haven't gotten to installing KDE yet, but I suspect the default driver is low res compared to a kld loaded driver. Do y'all know of a good driver for the MacPro video card?

pciconf -vl|grep -i rad
device = 'Tahiti PRO [Radeon HD 7950/8950 OEM / R9 280]'
device = 'Tahiti HDMI Audio [Radeon HD 7870 XT / 7950/7970]'
 
Well, all I can say is, wow, 2560x1440 looks pretty good on freebsd :)

Here's the fix:

Bash:
sudo vi /boot/loader.conf
hw.syscons.disable=1

sudo vi/etc/rc.conf
kld_list="amdgpu.ko"

Apparently, there's a conflict between the framebuffer driver and the amdstuff - see here for more info.
