Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I'm trying to install a PCIe TV Tuner card (Hauppauge WinTV-HVR-1800). It's detected during bootup but from dmesg it looks like I'm out of memory-mapped I/O space. I've increased the kernel's allocation space with the 'vmalloc=' boot command but it didn't change anything. Could someone tell me:
1) if I'm correct and the problem is insufficient MMIO space
2) Can this be solved by installing a 64-bit OS or am I out of luck completely?
Outputs of 'lspci -v', 'dmesg', 'grep Vmalloc /proc/meminfo', and 'cat /proc/iomem' are included.
Feb 27 17:37:02 localhost kernel: cx23885: can't get MMIO memory @ 0x0
Feb 27 17:37:02 localhost kernel: CORE cx23885 No more PCIe resources for subsystem: 0070:7801
Feb 27 17:37:02 localhost kernel: cx23885: probe of 0000:04:00.0 failed with error -22
I'm running Mythdora x64 10.21. I also see "could not get card info for card #0 subtype: Unknown error" in the Capture cards section MythTV-frontend.
I guess I should feel a bit embarrassed that I didn't try this earlier, but I'm so thrilled I don't care. Thanks very much for your quick reply Electro it definitely helped me out. With the flags in grub I was able to get my system booting much faster, I guess it was timing out on the PCIE resources(or lack thereof). Even after that, the card still would not work, but when you said "Probably it is a badly written BIOS" I finally decided to upgrade the BIOS. All seems to be well now, even without the flags in menu.lst. I'm now going to get it out of the computer room and into the living room. Thanks a bunch!
