The problems that were happening with mini-beep.iso for me earlier had lots to do with too ancient software meeting too modern hardware. Kernel drivers for ethernet cards weren't available for the right cards and the installer was telling me modules weren't available for the version of software that was being installed on several mirror sites. I think the first problem caused the missing modules symptom now. Until I can get a more up-to-date accessible debian installer I'm not going to be doing anything more with debian and especially not anymore with sid.
