Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

The approach is fine. 
I think (have not checked the PROTO versions) that -pre8 is _not_
protocol compatible to 0.7.x . (But simply compare the PROTO
versions, you can find them in the changelog and /proc/drbd.

There are a few fixes for 64 bit aches that were commited
into SVN after 0.7.5. I guess you should wait a week till I 
release 0.7.6 [ Or you convince me to do it faster... :) ]
