Correct.
using a ramdisk arrangement which I configured by launching the kernel with a bootm <address of kernel image> <address of ramdisk> and informing the kernel within the bootargs of root=/dev/ram, how should I pass the location of the root filesystem to the kernel?
You must pass a "root=/dev/mtdblockX rw" argument to Linux. Either your kernel then has built-in knowledge about the flash partitions (via a static mapping driver in drivers/mtd/maps/<board>.c), or you provide the partition information as part of the boot arguments, see http://www.denx.de/twiki/bin/view/DULG/BootTimeConfigurationOfMTDPartitions
In general, the DULG contains some hints :-)
