Aliens ate my brain, part 2:

My IPv6 configuration evaporated, totally, out of my .config. I tracked it
down to wierdness with net/Kconfig:

if INET

source "net/ipv4/Kconfig"
source "net/netlabel/Kconfig"

endif # if INET

source "net/ipv6/Kconfig"

(Yes, the ipv6 is now *outside* the if/endif - that's what I had to do to make
it work). If that last 'source' was *inside* that if/endif, it became
invisible unless I set INET to *N*, at which point ipv4 and netlabel would
disappear, and ipv6 would become visible. If I set INET to Y, then ipv4 and
netlabel would come back, and ipv6 would go poof again. This affected both
'make menuconfig' and 'make [silent]oldconfig'.

.config follows. I have *no* idea what caused it.

Possibly my (bad) gfs2/dlm patch...

Please try applying Adrian Bunk's patch to see if that fixes the
IPV6 disappearing trick. (below)

Unable to select IPV6. Menuconfig doesn't offer it when INET is selected.
When it's not it appears in the menu, but after state change it gets away.
The same behaviour in xconfig, gconfig.

Maybe this is the problem?

Yes, patch below.

This patch fixes a circular dependency by letting GFS2_FS_LOCKING_DLM
and DLM depend on instead of select SYSFS.

Since SYSFS depends on EMBEDDED this change shouldn't cause any problems
for users.
