It is not a problem. The *kernel* does not load jfs.ko, it is loader itself. There is no reason why a trivial non-gpl jfs reader couldn't be written for boot2 and loader if the need was great enough. Or have /boot as a seperate file system (eg: UFS or FAT32). We do this on IA64 where /boot is a FAT32 filesystem (not exactly, but close enough. I usually mount it on /efi and make /boot/ a symlink to /efi/boot so that in EFI we have a /boot as well).
