freebsd stable - Sep 2009 - Build kernel failure

Hi,

I have installed FreeBSD 7.2 on an old laptop. It's only for fun and
learning.

I wanted to make my console use full 1024x768, so I followed this howto:

http://kimklai.blogspot.com/2007/05/howto-freebsd-console-framebuffer.html

# make buildkernel KERNCONF=GENERICVESA
Gives me after quite long time this error message:

make: don't know how to make /usr/src/sys/sys/gdefs.h. Stop
*** Error code 2

Changes to GENERIC:

+options VESA
+options SC_PIXEL_MODE

-options SMP
-device apic
-device eisa

I would like to disable things I don't need, because the laptop is quite
old and slow and don't have too much RAM.

The laptop is an old Dell Latitude CPt C-series, 400MHz PII, 256 MB RAM,
6.5GB HDD.

If I succeed I will try to disable other thing in the kernel to optimize
even more. But perhaps I managed to disable somethig vital?

TIA,
Mikael

Responding to myself.
I reactivated the above options, and now I get a different error:

/usr/src/sys/dev/aic7xxx/aic7xxx.c:7896: internal compiler error: in
output_constructor, at varasm.c:4311
[snip]
*** Error code 1

I installed kernel source using sysinstall using an FTP mirror as
described here:
http://www.freebsd.org/doc/en/books/handbook/kernelconfig-building.html

Did I perhaps miss installing something?

TIA,
Mikael
