I wrote a buildsystem for grml-kerneladdons which allows me to build the appropriate package for every single kernel version of grml much faster now. So you can grab grml-kerneladdons for the first release of 2.6.18-grml already. Notice that the package is named grml-kerneladdons-2.6.18. This provides the possibility to install several kernelpackages at the same time without any conflicts. The package includes tpm-emulator and ipw3945 as well now.
