Yes, uLE won't load its config from HDD. To do this, it would have to load the HDD modules before it does anything else so it can load the settings from there. For now I'll recommnd using the hacked OSD settings and the override keys to launch brew from FMCB regularly. I have ESR set for autoboot (which works nicely on 1.91) and I set uLE to L1, a small power off ELF to R1, OPL to L2, and OPL+GSM to R2.
