Add additional parameter 'SYSLINUX_KERNEL_ARGS' in order to allow
for specific kernel parameters to be set when using syslinux.

Why would you use this and not APPEND? (or am I totally
misunderstanding something?)

A few more lines of context would have helped. Here is the code just after the
patch.
if append:
cfgfile.write('APPEND ')
if initrd:
cfgfile.write('initrd=/initrd ')
cfgfile.write('LABEL=%s '% (label))
cfgfile.write('%s %s\n' % (append, btype[1]))
else:
cfgfile.write('APPEND %s\n' % btype[1])
The extra kernel parameters are added to btype[1] and then written out as part
of the APPEND field.
Does that make sense?
