What about loading that driver with an /etc/X11/xorg.conf file?

Maybe you also need libglx package?

a little update: I tried to configure the xorg.conf file but there is not such file in our distro, so I created a file as suggested but the system did stop to work.

After two days of search, I did install the linux-free-firmware that (it seems) contains the firmware for the radeon gpu card. When rebooted I noticed no complains about "acceleration disabled", but the screen was frozen on startup as usual.

Then I searched for a way to make the video at least usable, so I stumbled on this post on MacRumors:"Modern Xorg on aniBook G3 Snow:Solved!" and applied that "fix".

Now the screen is at least reusable, but in my case glxgears returns this error:"

radeon: Invalid PCI ID.
libGL error: glx: failed to create dri3 screen
libGL error: failed to load driver: radeonsi
radeon: Invalid PCI ID.
libGL error: glx: failed to create dri2 screen
libGL error: failed to load driver: radeonsi

I bet this "fix" plus the mesa-amber package could fix this issue, but I can't select the mesa-amber packages (dunno how to do, but I tried the mesa-amber.sh thing).

@sergio I assumed you had those firmware packages installed. There are more on my website which get installed if you install MintPPC the usual way.
