OK, so it will be some another case.

There will be helpful additional information - does work USB at all?
I.e. when You connect e.g. USB flasdisk, is it working, can You use it
in GRUB?
(Sorry if it is not possible to try such situation, I never seen
loongson (fuloong) mini-pc...)

No, it does not work.  pmon handles it correctly, but grub provides the error disk not found, :-(
 

Another thing - You mentioned You used OHCI GRUB driver. As I see on
http://www.lemote.com/en/products/mini-computer/2010/0310/111.html ,
there is mentioned USB 2.0, i.e. it should be probably EHCI controller
- ?

I also generated image including the ehci module, and it didn't make a change...
 

(OHCI is USB 1.1 controller - but it could be used together with USB 2.0
EHCI as so called companion controller).
Is it possible that Your Mini-PC has USB 2.0 only (i.e. EHCI) controller
(without companion controller)?
Are somewhere available more detailed information about Your loongson-2f
Mini-PC HW?

I'm attaching more information about the mini-pc...  Notice dmesg indicates linux used ohci for this device without problems:

% uname -a
Linux mini-1 3.2.0-4-loongson-2f #1 Debian 3.2.32-1 mips64 GNU/Linux

% dmesg
