yast and kernel upgrades

i'm running 10.0 with a custom kernel 2.6.16.2. when i did a kernel update with yast, the system downloaded and applice several kernels older than 2.6.16 why is this? its not right is it for yast to put an older file than i had. -- Edward Dunagin-Dunigan 4646 Glenwood Drive Bozeman, MT 59718 mobile 406-570-0992
