Dear Rogan Dawes,

For some reason, the kernel didn't seem to think it had been given the ramdisk parameter. At least, I get the following error message:
Where is the ramdisk located? Make sure it is loaded into RAM (not flash!).

Hi Wolfgang,
The ramdisk is located at ff9a0000 (in flash). Its image header relocates it to 00800000:
From the vendor u-boot:
## Loading Ramdisk Image at ff9a0000 ... Image Name: Ramdisk Image Type: ARM Linux RAMDisk Image (gzip compressed) Data Size: 5240600 Bytes = 5 MB Load Address: 00800000 Entry Point: 00800000 Verifying Checksum ... OK
And from mine:
DNS323B1> setenv verify no DNS323B1> run bootcmd ## Booting kernel from Legacy Image at ff820000 ... Image Name: Linux-2.6.12.6-arm1 Image Type: ARM Linux Kernel Image (uncompressed) Data Size: 1490204 Bytes = 1.4 MiB Load Address: 00008000 Entry Point: 00008000 ## Loading init Ramdisk from Legacy Image at ff9a0000 ... Image Name: Ramdisk Image Type: ARM Linux RAMDisk Image (gzip compressed) Data Size: 5240600 Bytes = 5 MiB Load Address: 00800000 Entry Point: 00800000 Loading Kernel Image ... OK OK
0x800000 is well within the 64MB that the device has.
