yes, completely sorted in fact on those models... 997.2 and 987.2 are immune.
M96 and M97 engines have the issue. The M97 less so. The new engine 9A1 that came out in 09 models has no intermediate shaft at all, so no IMS bearing, problem solved.
So anything up to a 1998 993 and anything after (and including) a 2009 model year 911 or boxster or cayman is safe in that respect (there are other things you may worry about if you want, such as DFI).
99-08 is the trouble zone, but it is a matter of degrees. M96 engined cars (98 or 99-04 deopending on where you live, commonly 986s and 996s but also some early 05 997s in some cases, the cutoff is fuzzy) have a troublesome bearing but *can* be retroffited with a new one (LN etc) at clutch change time for a couple grand. I've seen one such 997 with my own eyes, wish I'd bought it as they are substantially cheaper than 997.2s... In truth those replacement bearings themselves have not been out all that long so there is no long term data on them either ;-)
05-08s (997s / 987s) have a bigger bearing that cannot be retrofited without splitting the case because of its larger size, but supposedly fails less often (but still does occasionally).
The brit mags report that the S models are more prone to it (3.8 997). have not seen that mentioned as much on this side of the pond.
GT3s and Turbos are exempt from this hoopla on account of a different bottom end.
Still confused ?
