Unfortunately syscons uses 800x600 with 16 colors (4 bit, mode 258) and all 
ATI cards I know don't support that mode, only 800x600x8 (256 colors, mode 
259). You can check your card features with 'vidcontrol -i mode'.
I'm no programmer, otherwise I had patched syscons to use mode 0x103 (259) 
instead of 0x102.
Perhaps you are lucky and find somebody who corrects this.
ALso, search the archives, some months ago some good guys made syscons use 
higher resolutions, perhaps they also implemented more sensful mode
