T400 and WWAN cards

[mwr]

Dear All,
Dear Zender,

I have Lenovo T400 (2765 22G) with the SIM module ready, I bought new OPTION GTM-378E WWAN 3G card unlocked.
After rebooting I got error 1804 and the system is unable to work unless I uninstall the new card.

After searching online, I found that it is something related to Lenovo, and that only cards from Lenovo are accepted.
Is there any way to bypass this BIOS protection ?

Please advice
