Do you have a POST card? If so, set up a post code at the start of w83977af_early_serial() so you can make sure LinuxBIOS is in fact making it that far. Do a post code with outb(0x[code], 0x80);
For this question the POST is Power-On Self-Test, but I don't know what is the POST card !!!
POST codes are codes sent to port 0x80 while the computer is booting (POST-ing), which can then be detected by an ISA or PCI card, and usually are displayed on an LCD screen. Like this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16815158065
They're also sometimes called PCI debug cards or port 80 debug cards. And you can get them for much cheaper than the one I linked to, I spent like $9 on mine on ebay, with shipping.
