The bug is that syslinux incorrectly positions the stack above the command line (but not the stack pointer register; hence the kernel patch exposing this bug.) So the stack plus command line end up being limited to 512 bytes; how much stack gets used depends on the BIOS, so one BIOS may use a lot more than another.
