These images include card services 2.7.6. Our 2.0 and 2.1 images only have card services 2.6.3a. 2.7.6 has some bug fixes and supports a few more cards. In particular, the 3Com 562 is supported with these images. Use them with a stock ramdisk1 image from 2.0 or 2.1. In addition, after installing you will need to update the card services package from any RedHat mirror.
