Thanks Masood.

I've run into a strange problem on the 2950's - Both devices are 
C2950G-24-EI (Which support baby giants), but the one with the more 
recent IOS is only reporting that it supports 1500 byte mtu?:

Model number: WS-C2950G-24-EI System serial number: FOC0833X3M8

System image file is "flash:c2950-i6q4l2-mz.121-22.EA7.bin"

No baby giant support:

gc-sw-08(config)#system mtu ? <1500-1500> MTU size in bytes



Whereas:

Model number: WS-C2950G-24-EI System serial number: FOC1012Z5BJ

System image file is "flash:/c2950-i6q4l2-mz.121-22.EA6.bin"

Baby giant support:

ESW01-BNE(config)#system mtu ? <1500-1530> MTU size in bytes


I compared both images on the Feature Navigator, and there is no 
mention of any Features unique to the images other than "IEEE 802.1x - 
Auth Fail VLAN" on the EA7 vers.?
