This is _not_ a FreeBSD bug.  I think you just got lucky with 7.0, maybe the 
BIOS bug only corrupts data read from certain sectors on the CD and the 
kernel for 7.0 was in a different location on the CD.  This is a bug in your 
machine's _BIOS_.  FreeBSD can _not_ fix your broken BIOS.  Please 
understand, the reason you are having problems is that when the FreeBSD boot 
code asks the BIOS in your machine to read files off the CD, the BIOS is 
corrupting the files that are being read in some cases.  If it corrupts the 
kernel, then of course you are going to run into issues.  However, there is 
nothing FreeBSD can really do about this.  We depend on a minimum subset of 
the BIOS functioning correctly, including reading files off of disk drives.
