One of the biggest issues regarding the mips based Linkstation seems to be solved! According to this thread and this detailed howto, a guy from linuxnotincluded managed to port the u-boot bootloader to the mips Linkstation. Now it should be possible to build and boot a custom kernel having all the desired bells and whistles like inotify support, bluetooth support, xfs support any everything else the 2.6 kernel can provide. I will now start implementing this on my Linkstation – keep fingers crossed that I don’t brick it ;-). The proceedure does not yet look trivial but I think its worth to give it a try to have the kernel available for further features.
