 	   This allows device drivers to enable MSI (Message Signaled
 	   Interrupts).  Message Signaled Interrupts enable a device to
 	   generate an interrupt using an inbound Memory Write on its
 	   PCI bus instead of asserting a device IRQ pin.

-config PCI_LEGACY_PROC
-	bool "Legacy /proc/pci interface"
-	depends on PCI
-	---help---
-	  This feature enables a procfs file -- /proc/pci -- that provides a 
-	  summary of PCI devices in the system. 
+	   Use of PCI MSI interrupts can be disabled at kernel boot time
+	   by using the 'pci=nomsi' option.  This disables MSI for the
+	   entire system.
 
-	  This feature has been deprecated as of v2.5.53, in favor of using the 
-	  tool lspci(8). This feature may be removed at a future date. 
-
-	  lspci can provide the same data, as well as much more. lspci is a part of
-	  the pci-utils package, which should be installed by your distribution. 
-	  See <file:Documentation/Changes> for information on where to get the latest
-	  version.

+	depends on PCI && EXPERIMENTAL && BROKEN
+	help
+	  Say Y here if you want the PCI core to spawn a new thread for
+	  every PCI device that is probed.  This can cause a huge
+	  speedup in boot times on multiprocessor machines, and even a
+	  smaller speedup on single processor machines.
 
-config PCI_NAMES
-	bool "PCI device name database"
-	depends on PCI
-	---help---
-	  By default, the kernel contains a database of all known PCI device
-	  names to make the information in /proc/pci, /proc/ioports and
-	  similar files comprehensible to the user. 
+	  But it can also cause lots of bad things to happen.  A number
+	  of PCI drivers cannot properly handle running in this way,
+	  some will just not work properly at all, while others might
+	  decide to blow up power supplies with a huge load all at once,
+	  so use this option at your own risk.
 
-	  This database increases size of the kernel image by about 80KB. This 
-	  memory is freed after the system boots up if CONFIG_HOTPLUG is not set.
+	  It is very unwise to use this option if you are not using a
+	  boot process that can handle devices being created in any
+	  order.  A program that can create persistent block and network
+	  device names (like udev) is a good idea if you wish to use
+	  this option.
 
-	  Anyway, if you are building an installation floppy or kernel for an 
-	  embedded system where kernel image size really matters, you can disable 
-	  this feature and you'll get device ID numbers instead of names.
+	  Again, use this option at your own risk, you have been warned!
 
-	  When in doubt, say Y.
