PXE and newer FC5/FC6 kernel problems

Hello, I've been running for some time now a setup where I have a tftp/dhcp/nfs-server and a diskless mediaplayer (stock Intel setup) on a local network. The mediaplayer has done a PXE-boot from the server and everything has been smooth. Both the server as well as the mediaplayer have been running FC5 with the 2.6.17-1.2187 kernel. The tftpboot-stuff has been created/managed with the system-config-netboot program. However the more recent kernels have had a number of problems, some still unsolved. For starters, the newer kernels require that I define ramdisk_blocksize=1024 as an additional boot-parameter. At the moment I can get the FC5 mediabox to boot up with the new kernel, but it now is unable to mount a number of directories, such as /var/lock and /var/run, as readwrite. This of course wreaks havoc on the whole functionality. The said directories are mentioned in the snapshot/files-file, so there is something else broken in the whole setup. I also set up a basic FC6-installation to be booted from the server, but using that installation to boot the mediaplayer fails at a separate error. It complains that the /tftpboot/boot/mediaplayerfc6/root is not mountable, although I can NFS-mount this fine from another workstation in the same local network. Creating the FC6 setup on the server with the system-config-netboot does not give any errors. Neither case gives off any errors in the server logs (messages/dmesg/secure). I'm a bit stumped at this point so I would really appreciate if anyone could give a hint where to look for next or whether I have missed something obvious.
