Actually I thought so firstly, but concluded that kernel option is
better in this case. Two reasons:
1. Re-initialize video BIOS code is written in asm.  I want to keep it
   to be small as possible.
2. People won't try to enable or disable the code so many times.
   They will specify the option only once if necessary.
