Have I understood the above correctly?
The radeon driver used in Trisquel 6 supports both UMS and KMS. The version
used in Trisquel 7 only supports KMS. The radeon kernel module is disabled in
both Trisquel 6 and 7. In Trisquel 6, that means that UMS is used instead of
KMS. In Trisquel 7, that means that the radeon driver cannot be used at all,
so the VESA driver is used instead.

The linked thread suggests un-blacklisting the radeon kernel module. That has
worked for some people, but not me. Why? Because of different cards?
What "firmware" are you talking about? Is it something non-free that has been
removed from linux-libre?
