The documentation claims that ACL's associated w/ physical interfaces may only 
have one mask, but this does not apply generally. However, you may be hitting 
CSCdz06177, which should be resolved in 12.1(9)EA1d.

For any of the L3 switches, you should always take time to look at the 
hardware-specific config documents for ACL's -- since they're handled in 
hardware, there's often many restrictions applied to them:

Good luck.
