Ah okay - is this a bug in the OpenBIOS implementation? My process for
debugging so far has been to turn off autoboot in OpenBIOS and then
stick a breakpoint on one of the CIF methods and go from there; however
this method seems much better!

I think you should be able to clear it (set it to an empty string) with:
dev /chosen
" " encode-string " bootargs" property
followed by:
boot cdrom
