[LinuxBIOS] 440bx stuff

Okay, I know you guy probably thought you got rid of me, but I'm still around. I'm currently trudging through everything I can find for docs on both the 440zx-66 and 440bx chipsets, and looking what's currently there for code and what exactly needs to be implemented. I still have the 440zx mobo (bios mod never worked out), and in the morning I should be able to get a 440bx, one that hopefully has a removable bios chip. I'm curious, is there any way to test the code through software, without a flash? Also, as far as POST cards go, any one thats better than the rest? Or just the cheapest thing I can find will work?

Its a C thing.  You can't start a variable with a number.  That allows
you to match the directory name to the struct statements in the code.

the e7501 datasheet has a date on it thats almost a full year earlier
than the 855pm.  I think the register names and operation may be closer
to the 440bx.  But feel free to use whatever.  Its mostly about framework.
