Promise 378 and ATA Raid

I'm new on this list.
I'm very interesting in dmraid because I get two hardware Raid chipsets
on my mobo (A8V Deluxe Wifi Edition). Also, I'm running Gentoo Linux
2005.0 with linux 2.6.11. On BIOS, with FastTrack utility, I've
configured my disks in RAID1 mode.
$ lspci |grep RAID
0000:00:08.0 RAID bus controller: Promise Technology, Inc. PDC20378
(FastTrak 378/SATA 378) (rev 02)
0000:00:0f.0 RAID bus controller: VIA Technologies, Inc. VIA VT6420 SATA
RAID Controller (rev 80)
Two (160GB) ATA Hard Drive disks are plugged on ATA Raid port. Another
(120GB) Hard Drive disk is plugged on primary master. The two 160GB
disks are known as sda and sdb.
So, Linux Kernel is configured with Promise 378, and SATA VIA but the
160GB HDD seem to be controlled by Promise 378. Kernel messages about
sata and promise are attached.
So I've done a :
$ genkernel --kernel-config=/usr/src/config-2.6.11-gentoo-r11 --udev
--dmraid --no-clean --lvm2 all
When I've run:
$ dmraid -ay
I get a new device:
So I've tried:
$ cfdisk /dev/mapper/pdc_gjbjdaggeon
but 80GB only are available, then I create a partition with whole space
=> $ cfdisk /dev/sd[a|b] shows only one 80GB partition and 80GB free
space on both disks.
that's why I'm wondering if it is possible to make more 80GB with dmraid?
