NetWinder TFTP installer - initrd exceeds ramdisk size

The current NetWinder TFTP boot.img fails to boot for me.
It seems that the uncompressed initrd exceeds the default
size of the ramdisk, see the log below.

The same image boots fine if I add "ramdisk_size=16384" to the
kernel command line.  This probably is not a good solution though,
as there are many NetWinders with only 32MB total RAM.

The boot.img was obtained from
linked from the installation manual at

$ md5sum boot.img 
0b3524a164317bcd6fa532bde4061a1a  boot.img

Here are the relevant boot messages, captured via serial port:

After which it quickly hangs.
