At first glance it appears that your 3.0-rc4 kernel configuration is missing something. Did you forget to build in support for VFAT (CONFIG_VFAT_FS) or the appropriate codepage (CONFIG_NLS_ASCII and CONFIG_NLS_CODEPAGE_437)? > Should I make another 3.0rc4 kernel with some specific config options set? > Would it be helpful to see all my config options in my 3.0rc4 kernel?

Second, compare your 3.0-rc4 with the 2.6.38 (or .39) config to see if anything is obviously missing. We can go on from there.
