CentOS - Dec 2006 - Cannot install driver under CentOS/ VMware ?

Trying the most basic 'vanilla hello world' kernel driver, install using
insmod,
and trying in module_init to do a simple kmalloc() fails,
kmalloc returns NULL - i.e. cannot allocate memory.

The driver loads fine under another non-VM system.

Is this a CentOS/VMware quirk ?
Does anyone know of a workaround or is it just a fact of life that you
cannot use insmod once the system is running ?
After all, the 'normal' kernel modules are able to load OK at startup.

Thanks,

MikeW

Should work fine if the kernels are the same ...
