  No, it genuinely went from working to broken
 And actually, I think my recollection is wrong.  I think
 it probably broke in 2.6.8-rt, and in mainline in either
 2.6.9 or 2.6.10.  Before that it worked fine, but we
 always used the system timer instead for RG because it
 seemed simpler (it was always 1000Hz then) and we
 stuck with that as the default and I guess rather
 abandoned the RTC option.  Sorry for being so lax.
 If it does work now, then of course, that's great.  
You need to get the users having the problem to retest with kernel
2.6.18 or 2.6.19-rc*.  Older kernels can't be fixed so what's the point?
