[Udpcast] File "/lib/modules/2.6.20.4udpcast/modules.pcimap" not found

Hello, I built an initrd image from Cast-o-matic last night, and I received the following errors on start: File "/lib/modules/2.6.20.4udpcast/modules.pcimap" not found (No such file or directory) then modeprobe: cannot parse modules.dep Using the busybox terminal, I saw that /lib/modules/2.6.20udpcast exists - so it seems like there's a mismatch (as initrd is referencing 2.6.20.4). I am using the latest available udpcast kernel (from the RPM).. any thoughts? Are the kernel & cast-o-matic out of step? Thanks, -Jeff
