Thanks for testing! I have built a 32-bit kernel with the revised assembler
and linker, and the readelf -u output looked good to me. I will install
the remaining two changes tonight (the assembler change was installed a couple
of days ago).
I haven't had a chance to boot the new kernel (waiting for a GCC build
to complete). There is a USB issue that appeared on my c3750 with
2.6.30.9 (2.6.30.8 is ok) and 2.6.31.5. Here is the dmesg output
from 2.6.31.5:

As you can see, there is a USB mouse and keyboard. Want to see backtrace
with new assembler and linker. However, at the least the first part is
consistent with the sysfs warning.
I "upgraded" this system to testing last weekend. The keyboard is broken
under X. In gdm/kdm, one has to press a key twice. The Xorg.0.log seems
ok:
(**) Option "CoreKeyboard"
(**) Generic Keyboard: always reports core events
(**) Option "Protocol" "standard"
(**) Generic Keyboard: Protocol: standard
(**) Option "AutoRepeat" "500 30"
(**) Option "XkbRules" "xorg"
(**) Generic Keyboard: XkbRules: "xorg"
(**) Option "XkbModel" "pc104"
(**) Generic Keyboard: XkbModel: "pc104"
(**) Option "XkbLayout" "us"
(**) Generic Keyboard: XkbLayout: "us"
(**) Option "CustomKeycodes" "off"
(**) Generic Keyboard: CustomKeycodes disabled
(II) XINPUT: Adding extended input device "Generic Keyboard" (type: KEYBOARD)
Mouse works ok.
Thoughts?
