for whatever reason the max. kernel command line size is
different on different archs:
./asm-mips/setup.h:#define COMMAND_LINE_SIZE 256
./asm-ppc64/setup.h:#define COMMAND_LINE_SIZE 512
./asm-parisc/setup.h:#define COMMAND_LINE_SIZE 1024
....
and there are patches that extend this value:
-#define COMMAND_LINE_SIZE 256
+#define COMMAND_LINE_SIZE 512 /* The boot commandline in Knoppix can
get quite long -KK Oct. 2002 */
