[HD2 Android SD Development] Drakknar:
If it can be useful, here's mine:

set mtype 2524
set ramaddr 0x11800000
set ramsize 0x1e400000
set initrd_offset 0x00a00000
set KERNEL zImage
set initrd initrd.gz
#EDITED by BANGSTERS, please mention me anywhere if you're using my changes. read the readme file how to edit this
set cmdline "rel_path=Android data_size=1024 lcd_res=240 conn_type=rmnet kernel_type=axi gps_zone=europe"
boot

Also, here's default.prop

ro.sf.lcd_density=180
rild.libpath=/system/lib/libhtc_ril_wrapper.so

and build.prop
