If you're feeling brave, I just back ported the all-singing /
all-dancing md device from -current today (I wanted a
size-configurable, non MFS malloc disk for something).  I haven't
pushed it very hard, but multiple disks appear to work from a module.

Apply the patch at http://people.freebsd.org/~gallatin/md.diff
Then grab sys/sys/mdioctl.h and sbin/mdconfig from -current.
You'll need to make the mdctl device node yourself (95, 0xffff00ff)

If anybody else feels like testing this, please do so.  Is there
some interest an MFC?

Cheers,

Drew
