Booting Kubuntu Trusty from either USB or DVD (Kubuntu > 700MB):
Daily ISO 2014.03.06 => Kernel: Linux kubuntu 3.13.0-15-generic #35-Ubuntu SMP  = not working
Daily ISO 2014.03.07 => Kernel: Linux kubuntu 3.13.0-16-generic #36-Ubuntu SMP  = working (without grub BL)

I'm very sorry for this mistake, reported 1 day to soon then...

Just downloaded the Kubuntu Trusty 2014.03.07, and it boots just fine
with syslinux + forcepae (with the 3.13.0-16-generic #36 kernel). Even
though booting (and installing) theese old boxes from buildin IDE-DVD
takes forever compared to USB stik (less than 2 minutes boot).

Thanks for the very fast response, and sorry for not dobbelt checking
the kernel version. We (users) are no even precentet with instructions
on how to boot these Pentium boxes, if omitting the forcepae parameter -
very polished indeed.

Title:
  Unable to start Ubuntu 12.04 live CD with syslinux loader on Pentium M
  x86 Laptop due to bug in PAE kernel, initramfs or syslinux

Status in “linux” package in Ubuntu:
  Fix Released
Status in “syslinux” package in Ubuntu:
  Invalid
Status in Baltix GNU/Linux:
  Triaged

Bug description:
  Ubuntu 12.04 doesn't start from Desktop CD or USB with syslinux boot
  loader on Pentium M 1.6Ghz or faster Pentium M CPU - displays error
  message about missing PAE feature in CPU, but *the same* *Ubuntu
  12.04* Desktop CD/LiveUSB starts fine on *the same CPU* (and same PAE
  kernel) if GRUB boot loader is used, for example when WUBI or LiveUSB
  with GRUB boot loader, like Multisystem
  (http://liveusb.info/dotclear/index.php?pages/install ) is used!

  The error message is:
  "This kernel requires the following features not present on the CPU: pae.
  Unable to boot - please use a kernel appropriate for you CPU."

  THIS IS AN IMPORTANT REGRESSION! People are able to install and successfully use Ubuntu 12.04 on such pretty new hardware, like IBM Thinkpad T42 laptop with Pentium M 1700Mhz processor, but the bug in syslinux (or something related) forbids Ubuntu 12.04 installation.
  This bug is reproducible on lots of computers, there are several log files and /proc/cpuinfo file attached to this bugreport, AFAIK it's enough to reopen this bug.
