[Fedora-xen] no Virtualization support for creating VM's on PE840‏

what it is is that i recently purchased a Dell PowerEdge 840 after carefully
selecting the specs i required, on its arrival i noticed that the BIOS does
not support virtualization, as a result of this on successfully installing
Xen vm on Open Suse 10.2 which creates the vm kernel and i try to start the
vm i get the error message:
'Cannot start the virtual machine'
then it goes on to say :
command: /usr/sbin/xm create /etc/xen/vm/vm1 return
  Error: (22, 'Invalid argument')
  Using config file "/etc/xen/vm/vm1".
 
when i prompt for more details i get:

'Error: HVM guest support is unavailable: is VT/AMD-v supported by your CPU
and enabled in your BIOS'
 
i have had a word with dell support who confirmed that the that the BIOS
does not support virtualization for now and that that option in the bios is
defaultly set to disable and that the most recent release of my BIOS
software doesn't list this in the menu for me to toggle that option, and
that maybe a future release of the BIOS software will have accessibilty to
this option. I was adviced by the Dell Engineer to come this site and seek
for help on this site.
 
does anyone know what i can do to get around this problem please.
 
i was told by the Dell engineer to run a cat command on the cpuinfo file to
see if the flag will reflect xt or vt, i did this and the i got the
following:
 
odi at PE840Srv:/proc> cat cpuinfo
processor       : 0

bogomips        : 4269.91
 
i badly need to create virtual machines on this server, its got 750 GB HDD
(mirroring support) and 8GB of RAM, i selected all this with virtualization
in mind obviously. 
 
any assistance will be greatly appreciated.
