XkbSetDetectableAutoRepeat not working on some platforms

XkbSetDetectableAutoRepeat is not working correctly on some distributions, including Ubuntu 9.04. In practical terms, this means programs running under Wine on such distros are unable to ignore autorepeat, doing strange things to games that use keyboard controls, for example. One way to work around the problem is to manually filter out the key release messages, which can be done with a few extra lines in dlls/winex11.drv/event.c . My question is, should I send a patch enabling this filtering? From what I have seen, patches to work around bugs that are clearly outside Wine are usually not accepted.

I'm adding the patch inlined in this message for those that might want to look at it; if I feel the patch do have a chance to be accepted I will resend to wine-patches.
