Yes,maybe Ubuntu kernel applyed some patch? Otherwise AMDGPU driver only worked on X86_64 ? The radeon drivers worked well on 32bit kernel. I have Caicos and Oland chipset radeon graphic cards,all be drived perfect on LFS-10.0 i686 arch!
It should work in theory. That said, we don't do regular validation of 32 bit any more.
