I just upgraded to 2.6.7, but this was true for 2.6.5 too. I'm using
Linus' original kernel...

On my server, which has RAID1, I have the raid code compiled into the
kernel.  AFAIK, it gets created by udev.  Using udevinfo, I can see that
md0 is a /block/md0, with these SYSFS information:
    SYSFS{dev}="9:0"
    SYSFS{range}="1"
    SYSFS{size}="690560"
    SYSFS{stat}="    1636        0    34472        0
		600583        0  4804664        0        0        0
		0"

For md1, I see these information:
  looking at class device '/sys/block/md1':
      SYSFS{dev}="9:1"
      SYSFS{range}="1"
      SYSFS{size}="267257088"
      SYSFS{stat}="   20071        0   261188        0
		  458504        0  3676670        0        0        0
		  0"

So the information does look like it is exported to sysfs.

On the workstation, I don't have raid code compiled in, and get no mdX
nodes created.
