Memory Pre-allocation (mem=xxx)

[David C. Chiu]

Thanks for your comment Wolfgang.

The driver in question is compiled as module, and the last time I
checked (a year ago) there isn't a way to pass an argument to a module
driver during boot time. Has this changed? The kernel is 2.4 series.

Pass an extra boot argument?
