NPTL support in 2.4 kernel series?

[Martin Kittel <debian@martin-kittel.de>]

Hi,

I am maintaining the packages of the MaxDB database system.

Recently upstream has converted the database kernel from 
linuxthread-style threading to NPTL. While -at least for i386- 
linuxthreads is still supported in MaxDB at this time, it will go away 
in one of the next releases.
As far as I know there is no NPTL support in 2.4 debian kernels (as for 
example in some RedHat 2.4 kernels). Is that correct?
In that case I will have to add a dependency on kernel-image-2.6 or does 
anyone know of a better way to express a dependency on NPTL style threading?

Thanks for your help,

Martin.
