[SLUG] problem with kernel compile

[Bill Taylor <norwest@xxxxxxxxxxxxxxx>]

hi all
was trying to make a new kernel : 2.4.19 + 2.4.20 patch
did make config, make dep, make clean without problems
then make bzImage. returned after some minutes and  a lot of text
\
          --end group  \
          -o vm linux
drivers/char/drm/drm.o:  In function  `sis_fb_alloc' :
drivers/char/drm/drm.o<.text+0x25df6>:  undefined reference to `sis_malloc'
drivers/char/drm/drm.o<.text+0x25e3d>:  undefined reference to `sis_free'
drivers/char/drm/drm.o:   In function    `sis_fb_free':
drivers/char/drm/drm.o<.text+0x25f82>:  undefined reference to `sis_free'
drivers/char/drm/drm.o:  In function `sis_final_context' :
drivers/char/drm/drm.o<.text+0x26456>:  undefined reference to `sis_free'
make:  ***  [vmlinux]  Error  1

I presume the error 1 means it didn't make :-( , I can only go back 
12-15 screenfulls of text
can't find any ref. to sis. the only other lines of interest (to me) is
{standard input}: Assembler messages:
{standard Input}: 1098:  warning:  indirect  lcall  without `*'  
with the number     ^^^ changing . 1098, 1183,1270,1354,1365, 1376, 
1467, 1479, 1491, 1989, 2082

I will try the config again. there where two references to sis in the 
config, can I drop one or both?
any help would be appreciated
thanks
