Understand, which is why I've asked there; they're not really sure why,

Ok, can do. (If you're willing to help with this, should I reply here,
or just to you? Are you on any other suitable mailing lists [i.e. the
PCMCIA one] I could instead send this to?)

Well, of course; I'm willing to do that work, I just have no idea what

(the first being 2.6.7, the second being 2.4.27).
If there's any other information I can apply, let me know.

I'll have a look - thanks.
