Perhaps we should mark it as broken using #error? After all the ULE changes in 7.x is amazing and we do not want to have users to obtain bad impressions from the 6.x versions... I am not sure but some explicit warning message saying "ULE has been revamped in FreeBSD 7.x+ and will not be MFC'ed back to 6.x, please use SCHED_4BSD or upgrade to 7.x." seems to be better than having them to pursue the mailing list archive...
