This is the output of "dmsetup ls":
/proc/misc: No entry for device-mapper found
Is device-mapper driver missing from kernel?
Failure to communicate with kernel device-mapper driver.
Command failed
No, dmraid doesnt' create the devices (2.6.11-r9 with udev); I have
tried to rerun Gentoo with the old kernel (2.6.11-r8 with devfs) and
dmraid works. I don't understand, I've used "make oldconfig".

Ah, *now* I understand. This has nothing to do with software raid or
mdadm. Viewing the partition tables is also going to be completely useless.
Does dmraid do anything when you run it...is there any output?
What does "dmsetup ls" show?
Did it create /dev/sil_* instead??
