Kernel Compile Fail with 2.6.26 Drivers

[Delphi Real Estate <Info@delphi-real-estate.com>]

Can anyone tell me what I'm doing wrong?  I know that 'n' has problems in later drivers than in kernel 2.6.26, so I am trying to graft the 2.6.26 drivers into the 2.6.27 kernel.  Source:
http://git.kernel.org/?p=linux/kernel/git/iwlwifi/iwlwifi-2.6.git;a=summary

I moved the regular Ubuntu kernel 2.6.27.10's iwlwifi directory elsewhere, and copied in Reinette's.  But it will not compile, inexplicably:
...
  CC [M]  drivers/pci/hotplug/cpcihp_generic.o
  LD [M]  drivers/pci/hotplug/pciehp.o
  LD [M]  drivers/pci/hotplug/shpchp.o
  CC [M]  drivers/pci/hotplug/fakephp.o
  LD      drivers/pci/hotplug/pci_hotplug.o
  LD [M]  drivers/media/video/uvc/uvcvideo.o
  LD [M]  drivers/pci/hotplug/acpiphp.o
  LD      drivers/pci/hotplug/built-in.o
  LD      drivers/media/built-in.o
  LD      drivers/pci/built-in.o
make: *** [drivers] Error 2
#

This kernel does compile with its normal iwlwifi directory.  In configuring I only set the iwlwifi driver to be a module, disabled the 4965, and enabled the 5000.  I can't use the git kernel because I need the Ubuntu patches.

Is there any other way to get 5GHz 'n'?
