Well I started out opening /dev/vcs, lseeking to 64, and writing
a string. This "sort of" worked, but screen attributes got messed
up so the "blue" screen attribute 0x17 ended up eventually being
black.

/dev/vcsa != /dev/vcs !!!!

There are two different devices, as far as I remember, one is only for
the characters itself on the console, and one includes attributes as well ...

FYI Documentation/devices.txt:

0 = /dev/vcs Current vc text contents
1 = /dev/vcs1 tty1 text contents
[...]
128 = /dev/vcsa Current vc text/attribute contents
129 = /dev/vcsa1 tty1 text/attribute contents
