Yes, I'm running 7-current.

I applied your patch ecng-7c.diff and Jung-uk Kim, compiled kernel,
but got next kernel panic:
---
panic: blockable sleep lock (sleep mutex) 32 @ /usr/src/sys/vm/uma_core.c:1830
cpuid = 0
KDB: enter: panic
[thread pid 21 tid 100013 ]
Stopped at      kdb_enter+0x32: leave
---

And sorry for delay in answers. This is because to be sure I recompile
 kernel each time (with command /usr/src && make buildkernel
KERNCONF=GENERIC). If there is any way I can speed up this process and
be safe?
