When using fbsplash in suspend2-sources-2.6.19 make fails due to fbsplash
including config.h instead of autoconf.h. After patching
drivers/video/vesafb-thread.c
drivers/video/cfbsplash.c
drivers/video/fbsplash.c
to include autoconf.h 
Compilation fails with the following error:

  CC      drivers/video/vesafb-thread.o
drivers/video/vesafb-thread.c: In function 'ioperm':
drivers/video/vesafb-thread.c:43: error: 'errno' undeclared (first use in this

kernel config for suspend2-sources-2.6.19 with fbsplash

*** Bug 157764 has been marked as a duplicate of this bug. ***

linux/config.h is obsolete in 2.6.19

this should do the trick...

#if LINUX_VERSION_CODE <= KERNEL_VERSION(2,6,18)
#include <linux/config.h>
#else
#include <linux/autoconf.h>
#endif

you'll need to edit

drivers/video/fbsplash.c
drivers/video/cfbsplash.c
drivers/video/vesafb-thread.c

I changed as you suggested and got this:

drivers/video/fbsplash.c:20:5: warning: "LINUX_VERSION_CODE" is not defined
drivers/video/fbsplash.c:20:27: warning: "KERNEL_VERSION" is not defined

I changed config.h to autoconf.h in the 3 files and it compiles well. Thanks.

As mentioned in my initial report I did replace config.h with autoconf.h,
however the kernel still fails to compile.

I changed
#include <linux/config.h>
to
#include <linux/autoconf.h>
in all the three files and now I get:

  CC      drivers/video/vesafb-thread.o

Miroslav, I also was getting your error.  There are two things I did to fix the
problem:

1. Copy the ebuild to your local overlay and change the version of the patchset
in the ebuild:

2. Edit drivers/video/vesafb-thread.c to include linux/freezer.h :
