Possible to flash a Medion NAS P89654?

Hello,
I own a Medion NAS with 2x4TB WD Harddisk Model WDC WD40EZRX-22SPEB0.
I studied the forum about flashing several NAS to use Debian on it, but I'm unsure if my NAS has the possibility to do it.
I have root access to my box and was able to install ipkg and other (so it can be used like an open stora.)
The kernel is based on HipServ Axentra, version 2.6.31.8 (so very old...:-/)

Processor	: Feroceon 88FR131 rev 1 (v5l)
BogoMIPS	: 999.42
Features	: swp half thumb fastmult edsp 
CPU implementer	: 0x56
CPU architecture: 5TE
CPU variant	: 0x2
CPU part	: 0x131
CPU revision	: 1

Hardware	: Feroceon-KW
Revision	: 0000
Serial		: 0000000000000000

The mtd partition is

mtd1: 00600000 00020000 "uImage"
mtd2: 0f900000 00020000 "rootfs"

If you need more informations, do not hesitate to contact me and I will post more infos.
