I have a fairly simple Lazarus program, just a few edit boxes on a form

Using Linux Mint 9 (a fork from Ubuntu), Free Pascal 2.4.0 and Lazarus
0.9.28.2, all 64-bit versions, when I run the program from konsole (run
from within GNOME) I get the following messages, before the program
(appears to?) run correctly
[WARNING] Out of OEM specific VK codes, changing to unassigned
[WARNING] Out of unassigned VK codes, assigning $FF
Can anyone tell me what's going on? The only things I can find about VK
codes pertain to Windows.
Since the LCL is compatible with the Delphi VCL, lazarus needed to mimic
the virtual keycodes used in OnKeyDown/Press/Up on other platforms than
windows. To generate code compilable for different platforms, those
virtual codes need to be the same for every platform.
For the X based GTK1/2 some logic is added to map the keyboard layout
reported by the X server to the Virtual keycodes.
Modern distros nowadays tend to provide one keyboard map fitting most of
the available keyboards. This leads a map with over the 150 possible,
sometimes exotic keys.
From a software pov. the LCL cannot tell what kind of keyboard the user
has plugged in, so it maps all keys reported by the X server.
Since the number of free to choose virtual keycodes is limited, the
gtk1/2 logic runs out of codes for some of the exotic keys.
So if you happen to have a keyboard with say functionkeys F24-F48 and
those keys are mapped last by the X server, you may have problems in
Lazarus when detecting KeyUp/Press/Down.
Forgot to add that this message is removed in laz 0.9.30
