Not that I am aware of this. Perhaps somebody at AppliedMicro?

Yes, ddr_scan_option() can be used to supply a board specific fix. But a 
generic fix in 4xx_ibm_ddr2_autocalib.c would be much better of course.

Do you experience any possible DDR2 related problems on your 460EX/GT based 
boards?
 
Cheers,
Stefan
