Thank you for the answer!

I don't have any firmware on the board. The boot loader (u-boot)
initialize the units: CPU, Memory, PCI, etc., but does nothing with
Graphic adapters. I can see only that, the video card is found on PCI
bus ("lspci -v" give to me: Class 0380: 1002:5940 (rev 01) - Radeon 9200
Pro). The very first interaction with the card is xorg's radeon driver.
Now I see why no picture appears before or after X server starts.

Are there any driver, or some another possibility, trough I can make
graphic low-level initialization before X server or kernel fb device?

Thank you in advance!
