According to Thomas Hirsch, the MX board bringup will continue pretty much where the LX board bringup left off (+ some rework of memory interfaces), which means a substantial part of the firmware is already there.

This is the last status list that was posted to the LX board thread on the Natami forums:

Code:
       Frame generation .......... ECS, fixed 28MHz pixel clock
       SyncZorro Interface ....... preliminary version
       Copper .................... fully implemented
       Video DMA ................. fully implemented
       256 color registers ....... fully implemented
       Sprites ................... 16bit linebuffer
       blitter ................... basic implementation.
                                    Block and fill mode done, line to come
       Video priority ............ half implemented
       Scandoubler ............... fully implemented
       Interrupts ................ fully implemented
       Paula DMA control ......... fully implemented
       Audio out ................. fully implemented
       VGA out ................... working
       DVI out ................... o
       PCI ....................... o
 (new) IDE ....................... fully implemented
       CIAs ...................... fully implemented
       Disk DMA .................. 880k and 1790k, read only
       Serial Port DMA ........... o
       Slow peripheral I/O ....... fully implemented
       (Joy/Mouse/Keyb/PRT/DSK/SER)
       PC mouse and kbd support .. o
       Fast RAM controller ....... o
       Kickstart flash logic ..... o
       Battery-backed up clock.... o
       15k Video out ............. o
       15k Video in .............. o
       Audio in .................. o
On top of that comes the SuperAGA modes and N68050 (though with the option of using the 68060 daughterboard instead of the N68050 core), which I believe they've stated they already have working on non-natami FPGA dev boards.
