The patch applied cleanly, but 'make depend' in compile/{CONFIG} gives me:

#    create  LOAN8DRM/ati_pcigart.d
mkdep -f ati_pcigart.d --  -ffreestanding -fno-zero-initialized-in-bss

Otherwise, I was impressed yesterday when I finally decided to switch
one of my old laptops to -current (mainly as a server, not required
otherwise) : - radeondrm worked straight after installation, gave me
some reasonable glxgears figures (~140fps, but this is 5 y/o IGP 200
or something). I don't remember whether I used one of the ISOs from
releng or a slf-built one on this occasion, but it looks just fine.
