ok, I mailed the tech@ group last night and got a response from Theo, initially the response was..
Wierd. I've never seen this (these) patches before.
and after he did a little more digging, when I mentioned that Miod had also proposed a an alternate fix...
There are large problems with our wscons keymap stuff not being able to deal with that nightmare of a keyboard. It is rather ugly to deal with.
Yes, talk to him in a few weeks, and keep talking to him every 2-3 weeks.
A translation of that for the folks that haven't spent time with the wscons source code is really that wscons (as is most of the Kernel source) is actually quite cleanly and simply implemented. It is good clean code, nicely written and easily read but doesn't handle the case scenario for wierd keyboards that don't have dedicated lock keys such as Caps or Num lock.
My fix implements the Caps Lock in an early part of wscons and duplicates some effort that the wscons driver performs a little later so it is feasible that a good rework of wscons could handle this keyboard and a few others in a nice clean manner that doesn't offend the standards of the project. For now that means that the patch is 'apply it seperately' if you need it and if you don't then don't bother.
Note that the code we are considering for the wscons fix is core OpenBSD code and nothing specific to the Zaurus... Zaurus specific hacks for certain things would be ugly and perhaps only just bearable in the Zaurus specific portions of the tree, however, they would clearly be unacceptable in the main portion of the source tree.
X is a different matter, however, it seems that very few folks like the XOrg source and Theo makes no comment on that patch. XOrg uses raw keyboard handling and manages Caps Lock state independently of the Kernel state which is ugly in its own right.. it may be that Matthieu who maintains the XOrg part of OpenBSD could be swayed to take a look at the patch, however, I acknowlege that it is a little ugly in the way that it works and he may not have much time to fix it in a cleaner way.
For now the message really is if you want Caps Lock under Console and or X, consider implementing these patches.
