Yeah i saw that one too ... looked promissing that they have an
experiment-board to accompany it ... i asked ARM for some details on
available ARM11 boards but its reply is in queue so to say, so maybe i can
tell you more this week.

Quite so! well at least it would ``relieve'' us from some legacy code but
the pmap really ought to be a lot easier/cleaner yes... hmm... but if i'd
be able to get a board? if they suply a few to NetBSD for free ;) :-D

As far as i could see in their documentation the ARMv6 was in a way made
for SMP or at least with SMP in mind. I saw some mentioning of more
explicit support for semaphore's somewhere.. i'll see if i can dig it up
again.

:-D I would like one too!! :-D
