agpmode does nothing on pcie asics like yours.  I suspect something
else is going on.  Do you have the linux firmware packages installed?
Debian no longer ships firmware packages.  The radeon driver requires
firmware to enable acceleration, and the kernel will wait up to 2
minutes searching to firmware if it's not installed.  File a bug
(https://bugs.freedesktop.org) and attach your xorg log and dmesg
output.
