This thread describes what I saw quite some time ago when Radeon DRMKMS was first imported to NetBSD (almost-black-on-black video, only cursor visible, X works fine). My experience was with older Radeon hardware (Radeon 7000, ES1000 and other R100-class cards).
The solution at the time was to simply ignore R200 and earlier radeon cards. Now I wonder if something like the memory size might have been the issue as seen in this thread. I'll have to check the BIOSes of the affected machines to see if they have some similar settings (if they did, I don't recall now but I have a habit of setting video memory to a minimum when such option exists). That and find the part of the code that checks for the card type to disable ignoring R200 and below. -- |/"\ John D.
