I don't have nodes for partitions

Hi, my system is a gentoo with 2.6.7 love sources. I have tested other
kernels with the same result. I don't have patched nothing ( I think the
sources are patched). I don't have instaled nothing, the device-mapper
package is instaled. I have dmsetup command.
I compile the RC3 sources of dmraid, and here are some results:

----------------------------------------------------------------------------
-----------------------------Why I can't mount any partition?
The stripe size of my RAID is 64 Kb. Is correct the output of  dmraid???
What's the problem? kernel? udev?

Bye.

/dev/mapper/isw_someletters, but I can't mount them because I don't have the
nodes for the partitions. I don't have nothing more except "control" under
/dev/mapper/

In cae you see the partitions with "fdisk -l /dev/mapper/isw_*", dmraid
fails to discover them, unless you activated with dmraid's "-p" option.
