That was fixed painlessly.

Moving on...

Looked at the handbook which prompted me to add agp_load="YES" to
/boot/loader.conf. Okay, mea culpa for not thinking of the obvious.

Everything now points to Hardware acceleration being active:

$ dmesg | grep -i agp
agp0: <Intel 82443BX (440 BX) host to PCI bridge> mem 0xf4000000-0xf7ffffff at device 0.0 on pci0
drm0: <ATI Rage 128 Pro Ultra TF (AGP)> port 0x9000-0x90ff mem 0xf0200000-0xf0203fff,0xf8000000-0xfbffffff irq 11 at device0.0 on pci1
info: [drm] AGP at 0xf4000000 64MB
